Popular music is music that is commercially oriented and intended for a wide audience, usually in urban, technologically advanced societies. Unlike folk music, it is typically written by identifiable professional composers and performers and spread through commercial channels rather than passed on orally. Its history runs from the songs of medieval minstrels and troubadours and the music halls of the nineteenth century to the phonograph, radio, sound film, and digital streaming platforms of the present.
The field matters because popular music connects several areas of life at once. It is a major part of culture and art, a large sector of the economics of intellectual property and markets, a driver of technical change in recording and distribution, and a common way that people form social and personal identities. Its study also shows how globalization and technological change reshape who makes music and who hears it.
The entry describes what counts as popular music and how it differs from folk and art music, then traces its antecedents and its development through recording, radio, film, rock, soul, hip hop, and electronic dance music. It goes on to cover the structure of the music industry, digital distribution, the measurement of popularity, legal rights, and regional and global scenes, and ends with scholarly approaches and open debates.
Definition and Boundaries
Popular music is commercially oriented music, principally intended to be received and appreciated by a wide audience, generally in literate, technologically advanced societies dominated by urban culture. Its songs are typically written by known individuals, usually professionals, and they do not evolve through the oral transmission that characterises folk music. Its performers and authors are identifiable, and its works circulate through commercial channels such as publishing, recordings, broadcasting and live touring. It is also distinct from art music, which has historically been written for and performed before smaller, more specialised audiences. Many popular forms can be performed by people with little or no formal musical training, so the term is usually understood in terms of reach and distribution rather than technical difficulty.
The meaning of "popular" has shifted over time. In its older, broader sense, popular music was any non-folk form that acquired mass popularity, from the songs of medieval minstrels and troubadours to elements of fine-art music that were originally written for a small elite but later became widely known. Much music of the seventeenth and eighteenth centuries, now labelled baroque or classical, was broadly popular and was not enjoyed solely by the upper classes. The sharp three-way division into popular, classical and folk music is therefore a comparatively modern arrangement. It became pronounced after the Industrial Revolution, when genuine folk traditions began to recede and the popular music of the Victorian era and early twentieth century was dominated by the music hall and vaudeville, with waltzes and operettas at the top of the market.
Scholars have proposed several competing definitions. One typology distinguishes normative definitions, which treat popular music as an inferior type; negative definitions, which describe it as whatever is not folk or art music; sociological definitions, which tie it to a particular social group; and technologico-economic definitions, which tie it to mass media and market production. Each captures something real, but each also has limits. Counting sales of recordings or sheet music measures purchase, not listening, because repeated plays of the same work are not counted. Defining popularity by audience size or social class is also problematic, since social categories cannot always be applied accurately to musical styles. Critics have further argued that mass-produced music is chosen from a limited set of options by listeners who merely buy or reject what is offered, which challenges the idea that popular taste is freely expressed.
The role of named authors and professional performers remains a defining feature, but it is not the whole story. Stardom, personal image and the composer-performer relationship distinguish popular music from anonymous or communal traditions, yet many popular musicians are motivated by expression and creativity as much as by profit. The boundaries with neighbouring fields are also blurred. jazz began as a fusion of African American traditions in the late nineteenth and early twentieth centuries and was marketed as dance music in the 1920s, yet later jazz styles became specialised and artistic, so the same repertoire can be classed as popular or as art music depending on the context. Classical crossover, in which art-music works or performers are repackaged for mass sales, raises the question of whether a work's audience or its marketing defines it. The category of world music covers non-Western traditional and popular styles marketed to international listeners, and some genres, such as k-pop, are tied closely to a single national culture while also reaching global audiences.
Film scores and musical theatre represent further boundary cases. Film music is composed to serve dramatic purposes, but soundtracks are commercially released and can chart as popular hits, and many stage works fed into the mass repertoire. Tin Pan Alley lyricism was combined with European operetta to create the Broadway-style musical, which then supplied standards to the popular market. Whether such works belong to popular music depends less on their musical form than on how they are composed, distributed and consumed, which is why the definition remains contested.
Antecedents Before the Recording Era
Long before the phonograph, songs reached large audiences through three channels: live performance by travelling entertainers, cheap print, and the commercial stage. Medieval minstrels and troubadours sang at courts and in towns, but their songs depended largely on patronage and memory rather than on a market for copies. Historians therefore treat them as precursors of popular music rather than as commercial popular music in the strict sense.
The clearest early form of mass-circulated song was the broadside ballad. Broadside ballads are songs printed on one side of a sheet of paper and sold in the streets, town squares, and marketplaces of early modern Europe. They first appeared in the fifteenth century, shortly after the invention of the printing press, and they remained common into the nineteenth century in both Europe and America. Because printing on a single sheet of paper was the easiest and most inexpensive form of printing available, a sheet could be sold for very little. Most broadsides did not print musical notation; they named a familiar tune to be sung to the words, and often the person selling the broadside sang the ballad to promote their wares. Later, song broadsides were a common and inexpensive medium through which popular songs were commercially disseminated prior to the advent of sound recordings. Many of them reproduced songs that were also sold in other forms, which shows how print spread the same material across a wide public.
The Victorian stage added a more organised commercial layer. The music hall in Britain drew its audiences mainly from the working and lower-middle classes until the 1890s, and its bill mixed songs with acrobats, comedians, and other acts. Its songs were often sensational and bawdy, which made them popular with audiences and objectionable to reformers. Alongside the halls, lighter theatrical forms carried melodic material to the public. In Britain, the height of English-language operetta was reached by Gilbert and Sullivan, who had a long-running collaboration in England during the Victorian era. In Vienna, the waltz was the most profitable dance-based export. Johann Strauss's operetta enjoyed international success, and its waltz theme was later arranged as a concert piece. Dance composers also made a living by producing arrangements of operatic and operetta tunes for private and public performance, which turned stage hits into domestic repertoire.
In the United States, the minstrel show was the dominant mass entertainment before the Civil War. Minstrel shows were the most popular form of theatrical entertainment in the United States in the decades leading up to the Civil War. Beginning in the 1830s, white performers in blackface imitated and caricatured African American music and dance on northern stages. The format depended on a steady flow of new songs, and it created a demand that songwriters could supply. Stephen Foster, who is often described as one of the first American songwriters to earn a living from composition alone, became the most prominent figure of this market. While still an amateur songwriter, Foster realized that the minstrel stage was the key to securing an audience for his songs. His songs were also aimed at the parlour market. He recognised that the economic weight of the American middle class was growing, and that a livelihood in songwriting required appealing to that group.
Foster's career shows how printing and touring theatre worked together. Performers introduced new songs on stage, and publishers then sold the sheet music to audiences who wanted to sing them at home. In 1848, "Oh! Susanna" became a national hit following its performance by the Christy Minstrels, and the song was widely pirated by more than two dozen music publishing firms. The lesson was not lost on Foster, who had the potential to earn significant sums from songwriting and the need to protect his artistic property. His later arrangement with E. P. Christy gave the troupe first performance rights in exchange for credit on the sheet music, a deal described as the show would be the first to sing his songs, and in exchange, the songs' sheet music would include the credit "As sung by the Christy Minstrels." Foster's songs, including the parlour ballads, achieved great popularity during his lifetime and continue to be popular today, though his minstrel songs about African Americans have been controversial since they were written.
Sheet Music, Tin Pan Alley, and the Phonograph
For most of the late nineteenth century, a popular song earned its living on paper. Home music-making was the main market: after the American Civil War, piano sales in the United States reached as many as 25,000 instruments a year, and many buyers needed notated music to play songs they had not heard before. Many of the firms that supplied this demand were small. Publishers were often music-store owners or local printers who treated sheet music and instruction books as a side line, and publishing was spread across cities such as New York, Chicago, Philadelphia and Cleveland before the industry concentrated in New York.
By the 1880s and 1890s that concentration was well under way. The name Tin Pan Alley came to describe the New York publishers and songwriters clustered along and near West 28th Street, and later the wider publishing district that moved north along Broadway. Its name is often traced to the clatter of pianos used to audition songs. Publishers hired staff songwriters, bought songs outright and sometimes put their own names on compositions by others. They also relied on song pluggers, who performed new numbers in department stores and music shops so that customers could hear a tune before buying the sheet music. Irving Berlin and George Gershwin both began their careers in this role. Weak copyright protection made competition fierce: a hit published by one firm could be reprinted by rivals, and publishers often preferred to arrange regional editions with partner firms rather than litigate. A stronger collective licensing system did not arrive until the founding of ASCAP in 1914.
Sheet music was the measure of success, and the figures were large. Charles K. Harris's "After the Ball" (1892) sold about two million copies in its first year, and Billboard's early sales charts tracked printed music before recordings. Industry output peaked around 1910, when Tin Pan Alley and other publishers produced roughly 30 million copies. Retail chains extended the reach of the business: by 1918, Woolworth's stores alone were reportedly selling 200 million copies at a dime each. Publishers also paid little to many of the writers whose songs sold best, and the composer of a major nineteenth-century hit, Stephen Foster, earned little from the sheet music that circulated widely.
The phonograph was first demonstrated by Thomas Edison in 1877. His machine recorded sound as indentations on tinfoil wrapped around a cylinder, and it was later improved with wax cylinders. Cylinders held only about two minutes of sound, wore out after repeated plays and were costly and slow to duplicate. Emile Berliner's flat disc, patented in 1887 and based on a spiral groove, changed the economics of recording: a metal master could be used to press many identical copies. Disc machines were mass-marketed from the late 1890s, and the Victor Talking Machine Company's Victrola (1906), designed to resemble furniture, helped move records into middle-class homes. Edison continued to promote cylinders until 1913, and cylinder production ended in 1929.
Early recordings were treated as a means of promoting sheet music and were often released only after the printed version had peaked. Recording artists were paid differently from publishers' authors. In the early 1900s, only the biggest stars received royalties, while most performers were paid a flat fee per session and songwriters were paid per song by publishers. Opera singer Enrico Caruso began recording in 1903, and John Philip Sousa was among the first to receive royalties on records. The Copyright Act of 1911 required a royalty on records of copyrighted works. Record sales rose through the 1910s, with the recording industry reaching a peak of about $121 million in 1921, which shifted bargaining power toward the companies that made records.
Historians differ on when records overtook sheet music. Some accounts show printed music outselling records through the 1910s, with live performance remaining the main source of income for musicians, while others argue that electrical recording in the mid-1920s sharply reduced sheet-music sales. A further source notes that sheet-music revenue rose relative to recording revenue across the 1920s, so the shift was uneven rather than a single turning point. Sound film later weakened Tin Pan Alley's position, as studios began acquiring music and radio grew in influence.
Jazz, Blues, and Ragtime Roots
Ragtime was among the first African American styles to reach a national commercial market in the United States. Its syncopated rhythm drew on African-derived musical practice and was set against European forms such as the march and the waltz. Scott Joplin's "Maple Leaf Rag," published in 1899 by John Stark in Sedalia, Missouri, was sold to the publisher for a fee of fifty dollars plus a one-cent royalty on each copy of sheet music, a contract that tied the composer's income to sales. The piece sold steadily, and it is often described as the first song to sell a million copies of sheet music in the United States. Ragtime spread through vaudeville performers, touring theatre, and the piano-playing culture of middle-class homes, and it reached listeners through piano rolls as well as printed scores. Its popularity also owed something to minstrel shows, where the cakewalk, an earlier dance form rooted in Black communities, had become a stage attraction.
Blues developed alongside ragtime in the same urban entertainment economy, but its breakthrough on record came later. The turning point was "Crazy Blues," recorded by Mamie Smith and Her Jazz Hounds for Okeh Records in August 1920. The producer and manager Perry Bradford had argued that a Black audience would buy recordings of Black singers, and the record sold around 75,000 copies in its first month, mostly to Black buyers. Labels quickly began issuing blues and other music aimed specifically at African American customers under the commercial label "race records." Singers such as Bessie Smith, who was signed by Columbia Records in 1923, became major sellers through this circuit, and the Theater Owners Booking Association (TOBA) vaudeville circuit provided a touring base for many of them. For the first time, a Black artist's record sales were treated as a serious business case by the white-owned industry.
Jazz rose to national prominence in the 1920s. Its New Orleans origins were carried north by musicians who moved to Chicago and New York, and recordings made in the decade, most famously those by Louis Armstrong, shaped how the music was heard and imitated. Dance halls such as the Savoy Ballroom in Harlem, which opened in 1926, made jazz a social pastime for urban audiences. Radio broadcasts from venues like Duke Ellington's Cotton Club in the late 1920s extended its reach beyond those cities. White bandleaders, notably Paul Whiteman, presented jazz-derived dance music to broad audiences, and the commercial success of such work helped establish jazz-influenced orchestras as a mainstream product rather than a regional curiosity.
The swing era, which is usually dated from about 1935 to 1945, marked the moment when jazz became the central popular music of the United States. The conventional starting point is Benny Goodman's engagement at the Palomar Ballroom in Los Angeles in August 1935, where an enthusiastic crowd is said to have danced in the aisles. Big bands of ten or more players, with sections of saxophones, trumpets, and trombones, filled ballrooms, toured widely, and recorded hit singles. Radio offered inexpensive entertainment during the Great Depression, and the dance craze that accompanied swing, including the jitterbug and the jive, drew young audiences into the dance halls. The music continued to carry wartime morale during World War II, when orchestras led by Duke Ellington, Glenn Miller, and others were heard widely on radio and in military camps.
The decline of the big band was driven by several pressures. Touring a large ensemble was expensive, and wartime restrictions on travel and personnel made it harder to keep full bands together. A recording ban by the American Federation of Musicians from 1942 to 1944 interrupted the making of records, and during that gap singers with vocal backing gained prominence. Frank Sinatra's rise is the best-known example: his solo career developed as big bands lost their central place in the market. The crooner style, which relied on the microphone introduced for electrical recording in the mid-1920s, allowed singers to perform softly and intimately before a listener at home. Figures such as Rudy Vallée and Bing Crosby, followed by Sinatra, made the vocalist the public face of popular taste, and the star singer, rather than the bandleader, became the principal attraction in the postwar era.
Radio, Film, and the Mass Audience
Commercial radio
Commercial broadcasting in the United States began in 1920, when KDKA in Pittsburgh went on the air. The station was run by the Westinghouse Electric Company, which wanted regular programs that would create demand for the radio receivers it manufactured. Its first major broadcast, the returns of the 1920 presidential election, was followed by musical programs that showed listeners would tune in regularly. Within two years more than 500 stations were licensed, but fewer than two million American homes owned a receiver, so the early audience was small and concentrated in cities. Advertising gradually became the main source of broadcasters' revenue, and music was among the cheapest and most dependable content a station could schedule.
Radio changed which songs could reach a national audience. Before networks existed, a song's reach depended on local dance bands, touring performers, and sheet music bought by amateur pianists. Network broadcasting, which NBC and CBS organized in the second half of the 1920s, allowed one program to be carried by many stations at once. A band playing in a ballroom in one city could now be heard across the country, and a single singer could become familiar to listeners who had never seen them perform. This gave broadcasters, rather than local venues or publishers, a decisive role in deciding what counted as popular.
Sponsored programs and the hit parade
Sponsorship shaped both the format and the selection of music. Manufacturers paid for programs, often named after their brands, and their advertising agencies frequently influenced the content. The most influential example was Your Hit Parade, which began on NBC in 1935 and was sponsored by the Lucky Strike cigarette brand. Each week the show counted down the most popular songs, and the appearance of a number-one song became a public event. Its ranking formula was not published; it was described only in general terms, such as radio requests, sheet-music sales, dance-hall favorites, and jukebox play, and was administered by the sponsor's agency. For several years before trade magazines began publishing singles charts in the 1940s, the program was widely regarded as the most authoritative guide to popular taste. The show's sponsorship also determined which orchestras and singers were heard, so commercial interests effectively selected the performers who reached the public.
The relationship between broadcasting and record sales was reciprocal. Airplay promoted recordings, and recordings supplied the material for airplay. This created opportunities for abuse: labels and promoters sometimes paid disc jockeys to play particular records, a practice known as payola. Prosecutions in the 1950s targeted it, though critics later noted that enforcement was partly a reaction by the established music business against newer performers and independent companies.
Hollywood and the sound film
The arrival of synchronized sound transformed the film industry and, with it, the commercial value of song. The Jazz Singer, released by Warner Bros. in October 1927, was not the first film with synchronized sound, but its success established sound as the industry standard. Its Vitaphone sound-on-disc system reproduced a musical score and songs performed by Al Jolson, and a few passages of spoken dialogue. The film was still mostly silent, and its songs included "Toot, Toot, Tootsie," a hit from 1922. Its box-office performance encouraged studios to convert to sound within a few years.
The Hollywood musical then became a machine for generating hit songs and stars. Studios employed songwriters under contract, commissioned original numbers for films, and promoted the resulting songs through radio appearances, sheet music, and records. Performers were bound to studios through long-term contracts, which allowed a single studio to build a star's image across films, broadcasts, and recordings. Musicals of the 1930s, including those choreographed by Busby Berkeley and the films starring Fred Astaire and Ginger Rogers, presented songs that listeners then bought in other forms. The film industry thus connected screen entertainment directly to the market for recordings and printed music.
Broadway and the standard repertoire
Broadway supplied much of the repertoire that film and radio later circulated. Stage musicals were a major source of songs, and writers such as Jerome Kern, George Gershwin, Irving Berlin, Richard Rodgers and Lorenz Hart, and Cole Porter wrote for the theatre before many of them moved to Hollywood. Kern's Show Boat (1927), with lyrics by Oscar Hammerstein II, is often cited as a landmark in integrating song and narrative. Songs from these shows were published as sheet music, recorded by many artists, and performed on radio and in nightclubs. Over time a subset of these songs became standards, recorded repeatedly by different singers and bands and frequently outlasting the productions that introduced them. Taken together, these songs, which later came to be called the Great American Songbook, formed a shared reference point for vocalists and audiences in the New York and national markets.
Rock and Roll and the Youth Market
Rock and roll emerged in the United States in the late 1940s and early 1950s from a blend of rhythm and blues, country music, gospel, boogie-woogie and jazz. Rhythm and blues had been marketed mainly to Black audiences, and the term itself was a record-industry label. Its crossover depended on a few intermediaries. Disc jockey Alan Freed, working on a Cleveland radio station, is credited with popularising the phrase "rock and roll" for this music in the early 1950s. Black vocal groups added gospel harmonies to rhythm-and-blues rhythms, while white artists brought in rockabilly and country influences. The result was a style that could cross racial lines in the record market even though segregation still limited how far Black artists could get airplay.
The style's commercial importance was tied to the rise of the teenage market. After the Second World War, young people had more disposable income and more leisure time, and a distinct youth identity began to form around consumer goods, dance and music. Some white teenagers began buying rhythm-and-blues records and tuning into late-night radio, and the music came to be heard as a soundtrack for rebellion against the tastes of parents. The rock performer became a stock figure in this context: a singer whose physical presence, sexual suggestiveness and refusal of older norms were as central to the appeal as the songs. Record companies, radio programmers and later television producers all learned to target this audience, which made the youth market a permanent part of the industry's planning.
Elvis Presley was the figure who turned this regional sound into a national phenomenon. Born in Mississippi and first recorded at the Memphis label Sun Records, he signed with RCA Victor in late 1955, a deal that brought him a large sum by the standards of the time. His first RCA single, "Heartbreak Hotel", was released in January 1956 and became his first number one hit. The single sold more than a million copies, and RCA's promotion relied heavily on national television, including a debut on a network variety programme in January 1956. His performance on the Milton Berle Show in June 1956, with "Hound Dog", produced both enthusiastic teenage response and strong criticism from the press and religious publications. Ed Sullivan, whose variety show was a major Sunday-night institution, initially refused to book him, but later appearances in September and October 1956 drew an audience estimated at about 60 million. The episode showed how television could accelerate a single's sales and make a performer's image as important as the record itself.
The single was the main commercial unit of this period. Presley's releases were designed for the jukebox, the radio playlist and the teenage buyer, and advance orders could make a record gold before release; RCA reportedly received more than a million advance orders for "Love Me Tender" in 1956. Albums were less central to the market in the 1950s, and many of the period's hits appeared first as singles.
By the early 1960s, the British rock and roll scene, which had grown from American models in the late 1950s, prepared the ground for the British Invasion of the mid-1960s. British groups brought American rock and rhythm-and-blues material back to the American market, and their success on radio and television made the United Kingdom a central source of popular music. The Beatles were the most important of these groups. Their songwriting developed quickly from early singles to more complex work, and the influence of American records by groups such as the Beach Boys was evident in their studio experimentation.
The Beatles' treatment of the album format marked a further change. In the United Kingdom, their albums were full artistic statements, whereas in the United States Capitol Records often reassembled them with extra tracks, a practice that separated the British and American catalogues. After the band stopped touring in 1966, they made studio-based work that could not easily be performed live. Sgt. Pepper's Lonely Hearts Club Band, released in the United Kingdom in May 1967, is regarded by musicologists as an early concept album. It used studio techniques, orchestral overdubs and a wide range of styles, and it helped establish the album as the principal artistic unit of rock, a shift that pushed the single toward a secondary role.
Soul, Motown, and Genre Diversification
Motown and the industrial production of soul
Motown was the clearest case of African American popular music being produced as a repeatable industrial product. Berry Gordy Jr. started Motown in January 1959 with a loan from his family. The company's headquarters on West Grand Boulevard in Detroit combined a recording studio with office space, and it became known as Hitsville U.S.A. Hitsville U.S.A. was the nickname for Motown's headquarters at 2648 West Grand Boulevard in Detroit. Gordy's operation is often described as borrowing from the logic of the car factory, a link the label's name also alludes to.
The label's hits were made largely in house. Gordy relied on in-house songwriters to churn out many of his label's hits. The most important team was Holland–Dozier–Holland, whose members comprised brothers Brian and Eddie Holland and their friend Lamont Dozier. Their work for The Supremes and others produced a run of chart-toppers; in July 1964, they began a run of five consecutive #1 pop hits, including "Where Did Our Love Go" and "Baby Love." Production was equally standardised. The Funk Brothers were a group of Detroit-based session musicians who performed the backing to most Motown recordings from 1959 until the company moved to Los Angeles in 1972. Their players included drummer Benny Benjamin and bassist James Jamerson, and their playing gave the records their recognisable rhythmic profile. Producers such as Smokey Robinson, Mickey Stevenson, and Gordy himself completed the in-house system.
The strategy aimed at mass crossover rather than a niche Black audience. Many Motown acts were popular with both Black and White audiences, and found worldwide success. The system was not without friction. In 1971 Marvin Gaye recorded "What's Going On," and Gordy initially refused to release it because of its political lyrics which focused on the civil rights movement and the Vietnam War. The label later issued the record and its album. The move to Los Angeles in 1972 marked the end of the Detroit production model, as the company tried to compete with larger record labels that dominated the industry.
Singer-songwriters and the album as a unit
From the early 1970s, the dominant model shifted from teams of staff writers toward artists who wrote and recorded their own material. Carole King's career illustrates the change. For a decade she had written hits for other acts, and her solo album Tapestry (1971) is Carole King's multiple Grammy Award-winning solo album — the first to propel King into the public eye. It was released in February 1971. One commentator described King as representing the sea change from assembly-line songwriting teams to singer-songwriters. Joni Mitchell's Blue, Joni Mitchell's fourth album, appeared a few months later, and both records were recorded in Los Angeles and became touchstones of the movement. The movement's commercial success reinforced the idea that an authored album could sell well. Tapestry's critical and financial success encouraged other female singer-songwriters and gave them cultural space to express a distinctive female point of view through music.
The shift also changed the unit of musical production. Albums were increasingly planned as coherent statements, with sequencing, cover art, and thematic continuity, rather than as collections of singles. Record companies still relied on singles for radio exposure, but the album became the primary vehicle for an artist's reputation and for revenue, a pattern that strengthened through the 1970s.
Disco, nightlife, and backlash
Disco grew out of urban nightlife rather than from a single studio system. It grew out of the Black, Latino and gay dance scenes of early-1970s New York and became a rare space of freedom and self-expression. The name derives from the word for a dance-oriented nightclub. Its name derives from discotheque, the French word for a type of dance-oriented nightclub that first appeared in the 1960s. The DJ, extended mixes, and the four-on-the-floor beat became central to its sound and to later dance music.
Disco reached the mass market through a combination of clubs, film, and records. Steve Rubell and Ian Schrager opened Studio 54, a New York City discotheque that attracted many celebrities in April 1977. The film Saturday Night Fever opened in December of the same year, and its soundtrack pushed disco into mainstream radio and chart success. Its commercialisation provoked resistance: its popularity peaked in the late 1970s, and its commercialization contributed to the backlash against it.
The backlash culminated in Disco Demolition Night. The Chicago White Sox held a promotion in which fans received discounted tickets in exchange for disco records, and radio DJ Steve Dahl would detonate between games the collected records. An audience of over 50,000 attended, chanting "Disco sucks!" as Dahl set off an explosion that destroyed the records. Thousands of fans stormed the field, setting bonfires and damaging the field, leading to the second game's forfeit. Some observers have read the event as racist or homophobic, a reading that Dahl disputes. The disco mainstream faded after 1979, but its dance-oriented production survived in clubs and gave rise to house music, which in turn shaped the electronic styles discussed elsewhere in this article.
Fragmentation by format and audience
By the late 1970s and the 1980s, the American market was increasingly divided into formats defined by radio programming and listener demographics. Top 40 stations played a broad mix, while album-oriented rock, adult contemporary, country, and urban contemporary stations addressed narrower audiences. Trade charts were maintained separately for different genres, which meant that a song's reach depended on the format that played it. Punk, new wave, heavy metal, and later hip hop developed partly within their own circuits of clubs, fanzines, specialty stations, and independent labels. Motown and disco had reached across audiences; the later format system tended to keep genres apart, and it made the relationship between a genre's commercial success and its audience identity more explicit. This fragmentation provided the framework for the later specialised genres and for debates about the diversity of listening discussed below.
Hip Hop, Electronic Dance Music, and Sampling
Hip hop from the Bronx party to a global genre
Hip hop's origins are usually placed in the South Bronx in 1973. On 11 August of that year, DJ Kool Herc, a Jamaican-born DJ who had brought the sound-system tradition of Kingston to New York, played a back-to-school party in a recreation room at 1520 Sedgwick Avenue. Historians now stress that the culture had several founders and earlier outdoor events, but this party is the usual starting point. Herc's central technique was the "break," the percussive passage of funk and soul records. He played two copies of the same record on two turntables and moved the needle back and forth between them, which extended the break indefinitely. He called this the "merry-go-round." Toasting, or talking rhythmically over the music, was borrowed from Jamaican practice and developed into MCing. Together with DJing, breakdancing and graffiti, it formed the early hip hop scene in neighborhoods with large African American, Puerto Rican and Caribbean populations.
Rap moved from the block party to the record industry in the late 1970s, when the single "Rapper's Delight" (1979) became a national hit. In the 1980s, groups such as Run-D.M.C., LL Cool J and Public Enemy built the genre's sound around sampled loops, dense lyricism and political content. Over the following decades, rap went from a regional and then niche product to a central part of the mainstream. By the late 2010s, US industry measurements of consumption placed hip hop and R&B at the top of the market, and rap singles regularly led the Billboard Hot 100.
House and techno: clubs in Chicago and Detroit
House music took shape in Chicago in the early 1980s. The Warehouse, a club where DJ Frankie Knuckles played from 1977 to 1982, is the usual point of origin, and the genre's name derives from it. Knuckles extended disco and soul tracks by looping them on a reel-to-reel tape machine and layering drum machine patterns, notably from the Roland TR-808 and TR-909. Its audience was largely African American, gay and working-class, and it grew partly out of the underground that remained after disco's mainstream decline. Acid house, named after the Phuture track "Acid Tracks," emerged from the use of the Roland TB-303 bass synthesizer. Chicago producers and European DJs carried the style to clubs in Britain, Ibiza, Belgium and beyond.
Techno developed in Detroit in the mid-1980s. Producers Juan Atkins, Derrick May and Kevin Saunderson, the Belleville Three, combined European electronic music such as the work of Kraftwerk with the mood of a deindustrialising city. Their music was mechanical, futuristic and often stripped back. Techno was embraced more quickly in Europe than in the United States, and by the early 1990s it had become established in Germany, Belgium, the Netherlands and the United Kingdom. Electronic dance music (EDM) as a broader category, built around large festivals and DJ-led performance, grew from these club roots. It became a major commercial force in the 2010s, when DJs such as David Guetta, Calvin Harris and Avicii brought dance production into pop charts and stadium concerts.
Sampling as creative practice and legal battleground
Sampling means isolating a sound from an existing recording and reusing it in a new one. In hip hop, early producers used drum machines and early samplers, and later hardware such as the Akai MPC, to build tracks from fragments of soul, funk and rock records. Sampling made it possible to connect new work to older recordings and to create a collage aesthetic that became central to the genre.
Its legal status changed sharply in 1991. In Grand Upright Music v. Warner Bros. Records, the court ruled that Biz Markie's unlicensed use of a fragment of Gilbert O'Sullivan's "Alone Again (Naturally)" was copyright infringement. The opinion opened with the phrase "Thou shalt not steal," and it established the rule that sampling required clearance. Many artists and labels responded by seeking licences, which raised production costs and reduced the number of samples used. Bridgeport Music v. Dimension Films (2005), decided by the Sixth Circuit, went further by holding that even very short samples could infringe. Bridgeport had earlier filed roughly 500 claims against major labels in 2001. Courts have not been uniform, however. In a later Ninth Circuit decision in Newton v. Diamond (2004), a sample from a Beastie Boys track was held too brief to be recognised by an average listener, a result that partly reflects the continuing uncertainty over the de minimis principle.
Mainstreaming and the charts
Once rap and dance music had established commercial audiences, they moved into the charts. Rap artists regularly topped singles rankings, and rap-influenced production became a standard element of pop. In the 2010s, electronic production became common in pop and hip hop tracks, and sampling gave way in many cases to licensed interpolations and session-based recreations of older sounds. The movement of these genres from clubs and block parties into mainstream charts depended on radio, music video, streaming platforms and the licensing system that sampling itself had helped to shape.
Recording Technology and Production
Multitrack recording, which keeps separate performances on parallel channels so they can be balanced and combined later, is among the most consequential technical changes in popular music. Its early development is closely tied to the guitarist Les Paul. Much of the credit for the development of multitrack recording goes to guitarist, composer and technician Les Paul, who lent his name to Gibson's first solid-body electric guitar. Paul's early overdubbing was done on acetate discs, and the recording was "destructive" in the sense that the original recording was permanently replaced with the new, mixed recording when he worked with single-track tape. The decisive hardware came from Ampex. Ampex released the first commercial multitrack recorders in 1955, naming the process "Sel-Sync" (Selective Synchronous Recording). Sel-Sync allowed a musician to hear earlier takes while recording new parts in sync with them, which made layered arrangements practical.
Cost kept the technology in professional facilities for a long time. The first Ampex 8-track recorder, installed in Les Paul's home studio in 1957, cost US$10,000 – roughly three times the US average yearly income in 1957, and multitrack tape stayed largely within specialist studios for about thirty-five years. Atlantic was the first record company to use a multitrack (as opposed to stereo or three-track) recorder in their studio. Track counts rose steadily: mainstream large format analog multitrack machines can have up to 24 tracks on a tape 2 inches (51 mm) wide which is the widest analog tape available. Cheaper tape-based machines for home use appeared in the 1970s, and with them the idea that a band could record a demo without booking a studio.
Electric instruments changed the sound that multitrack tape captured. The solid-body electric guitar, promoted by manufacturers such as Gibson and Fender in the early 1950s, gave players a sustained, amplified tone that could be layered and processed. The amplified electric bass, introduced by Fender in 1951, did the same for the low end and became a standard rhythm-section instrument in rock, soul and funk. Both instruments depended on electrical engineering in the form of pickups, amplifiers and effects units, and their adoption redefined what a band sounded like on record.
Electronic instruments moved production toward the bedroom. The drum machine is the clearest case. The Roland TR-808 was introduced in 1980, and the 808 launched in 1980 with a list price of US$1,195. Roland marketed it as an affordable alternative to the Linn LM-1, manufactured by Linn Electronics, which used samples of real drum kits. The 808 was unpopular at first, because the 808 sounded simplistic and synthetic by comparison. By the time Roland discontinued it in 1983, it had become common on the used market, often selling for less than $100, and cheap secondhand units then became central to hip hop and electronic dance music. Though the 808 was unsuccessful, it was eventually used on more hit records than any other drum machine. Synthesizers, MIDI interfaces and, from the late 1980s, computer-based digital audio workstations (DAWs) such as Pro Tools replaced tape with hard-disk editing. A single producer could then assemble, edit and mix a record in a home studio, a shift that reduced the dependence on large commercial facilities.
Studio production became an artistic role in its own right. The producer shapes arrangement, performance, instrumentation and overall sound, and works with the musicians and sometimes writes material. The engineer handles microphone placement, recording and mixing, and the mixing and mastering stages then fix the final balance. Phil Spector's densely layered productions of the early 1960s and the experimental studio work of the Beatles with producer George Martin in the 1960s showed how the studio itself could become an instrument. In the digital era, the same division of labour persists, though one person often performs several of these functions.
Digital processing extended this control to the voice. Before 1997, pitch correction was relatively uncommon before 1997 when Antares Audio Technology's Auto-Tune Pitch Correcting Plug-In was introduced. The software was developed by Andy Hildebrand using auto-correlation algorithms originally used in seismic wave mapping for the oil industry. Its audible use in pop was not always intended as subtle correction. Cher's 1998 hit "Believe" used the retune speed at its fastest setting, and the robotic effect became a feature of the record. Critics argued that as Autotune spread through pop, hip-hop, and eventually every genre with a vocal booth, a loud chorus of critics argued it was cheapening the craft of singing. The complaint, boiled down, was about authenticity in music: if a machine can hit the note for you, what exactly are you being applauded for? Defenders note that it's possible to add pitch correction so transparently no one can tell it's being used, so its presence is often inaudible. Similar disputes accompanied earlier technologies such as the electric guitar and the synthesizer, and the debate over pitch correction is therefore a recurring question about where technical assistance ends and musicianship begins.
Music Industry Structure
Major and independent labels
Recorded music is dominated by a few conglomerates. Universal Music Group, Sony Music Entertainment and Warner Music Group are usually called the "Big Three" In the music industry, these entities are known as the "Big Three": Universal Music Group, Sony Music Entertainment, and Warner Music Group. In Billboard's "current share" measure, which covers music from the previous 18 months current refers to music from the most recent 18 months, the Universal group reached 36.82% in early 2025, ahead of Sony at 27.37%, while Warner stayed at 15.89% Universal Music Group boost its year over year market share by nearly three percentage points, to a 36.82% current share so far in 2025 ... Sony Music Group, which increased its own share year over year to 27.37% ... the Warner Music Group (WMG), largely remained static at 15.89% current share this year.
The independent sector's size depends on how it is counted. On a distribution basis, independents and artist-direct labels held a combined share that includes music measured on a distribution basis (i.e. that majors distribute, and the independent share based on an ownership share will therefore be higher. Major labels have also been buying stakes in independent companies, a trend that blurs the line between the two categories.
Roles within the industry
A record company's core functions are split among specialised roles. Artists and repertoire (A&R) staff scout and sign performers, match them with songwriters and producers, and shape the early direction of a project. Music publishers look after the compositions themselves. A music publisher protects the copyright of an artist's composition. They are responsible for ensuring that a songwriter or a composer receives payment when their work is used. Publishers are often part of a larger company; Music publishers are often included within a larger record company.
Managers advise artists on career decisions and negotiate their contracts, while booking agents and promoters arrange concerts, price tickets and market tours. Distributors move recordings to stores and digital platforms. Each role can sit inside a major, an independent company or the artist's own business, which is why contracts with one company can involve several of these functions at once.
Revenue flows
Income is generated from several linked sources. Recordings earn money from sales and streaming; compositions earn publishing royalties from reproduction and public performance. In the United States, publishing generated $6,2 billion in the U.S. in 2023, jumping 10,7%. The growth was primarily driven by the surge of performance royalties, connected to the rise of streaming.
Live performance is a separate stream, and it is large. Around 80% of live revenue comes directly from ticket sales, while brand sponsorships and merchandise generate another 20%. Merchandise and sponsorships are therefore a significant share of touring income, even if they are smaller than ticket revenue. Labels usually take a share of recording income, but they may have limited involvement in touring or merchandise, so artists often negotiate these rights separately.
Concentration and its effects
Concentration affects which music is promoted. Because the major groups own large back catalogues and have extensive marketing, distribution and licensing operations, they can fund global campaigns and secure placements that smaller companies find difficult to match. Independents can still reach large audiences, but they often depend on distribution deals with majors, which means the majors' priorities influence which acts gain visibility.
Concentration also affects which genres receive investment. Commercial pressures tend to favour styles with reliable sales and streaming numbers, while niche or experimental work may depend on independent labels or on a small number of specialised imprints. The balance between scale and diversity remains a continuing question for the industry.
Digital Distribution and Streaming
The move from physical media to digital files depended on compression. The MP3 format reduced audio files to a small fraction of their original size, which made recordings practical to store and transfer over the limited bandwidth of late-1990s internet connections. Early sites such as MP3.com, which launched in 1997, mainly hosted unsigned artists. The larger disruption came from peer-to-peer file sharing. Napster, which went online in June 1999, let users exchange MP3 files directly from one another's computers, with a central server indexing the files. Major labels sued, and a court order shut the original service down in 2001, by which point it had about 80 million registered users. Many of these were not active users, and the number of people actually sharing files at any one time was far smaller.
The effect on the compact disc was substantial, though its size is still debated. CD sales fell by more than 10 percent in 2002 and kept declining until about 2015, when recording industry revenues were less than half their pre-Napster level. Economists have disputed how much of this drop was caused by copying, since some studies found that file sharing had little effect in certain years and a clearer negative effect later.
The industry's response was licensed download stores. Apple's iTunes Store, which opened in 2003, sold individual tracks at a fixed price per song, a unit that albums had previously bundled. Apple's rights-management system stopped copies from being shared freely, which helped persuade labels to license it. The store became the highest-grossing music retailer in the United States and accelerated the decline of record shops. Subscription streaming services, which became prominent from the late 2000s, then changed the model again. Listeners paid a monthly fee for access to a catalogue instead of buying files. By 2025, streaming paid recorded music more than $22 billion globally, and Spotify reported a record $11 billion in royalties that year.
Playlists and Recommendation
Streaming services also moved the point of selection from the shop shelf to the interface. Spotify, the largest service, distinguishes between editorial playlists, such as New Music Friday, which staff editors build with local knowledge, and algorithmic ones, such as Discover Weekly and Release Radar, which are generated from each listener's behaviour. Spotify says its algorithms select and order content across search, home screens and personalised playlists, using many kinds of input. Some editorial playlists are partly machine-assisted, and editors are known to use performance data such as save and skip rates when choosing tracks, though the company has not publicly detailed how far its editorial process is automated. For artists, placement on these playlists has become a major route to streams, and the criteria for inclusion are only partly transparent. This has led to concern about a few gatekeepers controlling discovery, which connects to wider questions about market power and the diversity of listening.
Royalties and Economic Debate
Payments are the most contested issue. Per-stream rates vary widely by service: one 2026 comparison put Spotify at roughly $0.003 to $0.005 per stream, Apple Music at about $0.006 to $0.007, and Tidal at about $0.012 to $0.015. Rates in such estimates depend on subscriber mix, country and contract terms. The main structural dispute concerns how subscription revenue is divided. Under a pro-rata model, all revenue is pooled and each artist receives a share of total platform streams, so niche artists can earn little even if their fans are loyal. Under a user-centric model, used by Deezer in several markets, each subscriber's fee is divided only among the artists that subscriber actually played.
Recording and composition royalties are separate payments. Each stream can generate a master royalty for the owner of the recording and a publishing royalty for songwriters through publishers and performing rights organisations. The US statutory mechanical rate for streaming services was set at 15.3 percent of domestic revenue from January 2026. Critics also point to concentration: Spotify reported that 80 artists earned more than $10 million in 2025, compared with one artist in 2015, while the share of independent artists and labels in its royalty pool was roughly half. Supporters argue that streaming has expanded the number of artists earning a living from recorded music, and the debate remains open over whether it has changed the earnings of working musicians overall. Older recordings continue to earn streams long after release, so the value of back catalogues has become an important question for the industry as well.
Measuring Popularity: Charts and Certification
Chart formulas
The Billboard Hot 100 is the music industry standard record chart in the United States for songs, published weekly by Billboard magazine. Its ranking combines three kinds of data. Billboard describes the chart as ranking songs by streaming data tracked by Luminate, radio airplay audience impressions measured by Mediabase, and sales data compiled by Luminate. The mix has changed over time. Early in the chart's history, sales were weighted heavily, and Billboard's stated formula aimed for sales at 35–45%, airplay at 30–40%, and streaming at 20–30%, although the actual blend shifts from week to week. Billboard has not published the full formula, and when it last described the balance publicly, in 2018, it named streaming as the most dominant factor.
The counting window has also been revised. Since July 2015, the weekly tracking period for sales has been Friday–Thursday, and airplay moved to the same cycle in 2021. Rule changes have also altered what counts as a sale. In 1998, airplay-only singles were allowed to chart on the main Hot 100, and the retail component was reduced from 40% to 25% in the same period. Streams entered the Hot 100 in 2007, before the global launch of Spotify, and album charts began factoring in streams in 2014.
Album units and the 2026 revision
The Billboard 200 works differently from the singles chart. The Billboard 200 combines album sales, track-equivalent albums, and streaming-equivalent albums, with no radio airplay. Ten individual track sales from an album count as one album unit, and streams are converted into the same unit. Billboard does not count individual streams as individual "units." Instead, Luminate converts streams into equivalent units.
Starting with the chart dated January 17, 2026, the threshold was lowered. Previously, one album consumption unit was an album sale, 10 individual songs sold from an album, 3,750 ad-supported streams, or 1,250 paid/subscription streams. Under the new rule, each album consumption unit equals 2,500 ad-supported or 1,000 paid/subscription on-demand audio or video streams generated by songs from an album. The Hot 100 adopted a matching weighting of 1:2.5 between paid and ad-supported streams. Not every stream counts equally. Programmed streams from services that choose the songs for you count at a lower rate on the Hot 100 and do not count toward album units at all. Streams of user-generated uploads are excluded from Billboard's weekly charts entirely.
Certification
Certification is a separate system that awards status by volume rather than by weekly rank. Music recording certification is a system of certifying that a music recording has shipped, sold, or streamed a certain number of units. Its thresholds differ by format and by country. The threshold quantity varies by type (such as album, single, music video) and by nation or territory. In the United States, Platinum certification represents one million units sold. The count for singles is different from the count for albums. For singles, 150 on-demand streams equal 1 unit, while for albums the RIAA has counted 1,500 streams as one album unit regardless of whether they were free or paid, audio or video. Downloads of individual tracks also feed the album total, so the same listening can be counted toward both a single and its parent album.
Certifications are not automatic. Certifications are not automatic and record companies have to apply. The first RIAA gold record for a single was granted in 1958 to Perry Como's hit single "Catch a Falling Star", and the Oklahoma! soundtrack was certified as the first gold album four months later. National bodies have since adapted their rules. For example, the Dutch NVPI has certified paid and ad-supported streams but excluded free streams such as YouTube and social media since 2024.
Limits of charts and certification
Charts and certifications measure recorded activity within defined markets and time windows. They do not measure total listening, and the methods used to weight them are not fully public. Their rules also shape behaviour. Billboard has, for example, changed the rules to rectify how sales are counted with respect to album bundles with merchandise and concert tickets, which shows how the counting method can encourage specific marketing strategies. Because rules tend to reward particular kinds of consumption, such as paid subscriptions or the first week of a release, labels and artists have reason to design campaigns around the measured categories rather than around the wider audience.
Visual Media, Stardom, and Live Performance
Music video and the cable channel era
Promotional films for songs existed long before dedicated television channels. The Beatles often filmed elaborate performances and showed them on segments of programs like The Ed Sullivan Show. Before 1981, artists reached fans primarily through radio, concert tours, and record stores, while music videos were promotional novelties rather than centerpieces of marketing strategy.
That changed on 1 August 1981, when MTV began broadcasting as a cable service. A new cable television channel opened with the words "Ladies and gentlemen, rock and roll." Its first clip was "Video Killed the Radio Star" by the Buggles. Following the format of Top 40 radio, video disc jockeys, or "veejays," introduced videos and talked about music news. Cable operators were not convinced at first; the company behind the channel had to persuade skeptical operators that a 24-hour music video channel was a viable business, and most were unconvinced.
Over the following years the music video became a standard part of a single's promotion. The channel's awards show and later programming extended its reach well beyond music, but the core model, in which a song is released with an image attached, remained. Michael Jackson's short film for "Thriller" (1983) is often cited as a landmark that showed how a video could function as an extended piece of entertainment in its own right. The rise of video-sharing platforms later moved this function online.
Performer personas and celebrity
Because video and television make appearance visible to mass audiences, performers increasingly built public personas that combined music, fashion, staging, and a recognisable image. Artists such as Elvis Presley, the Beatles, and Michael Jackson each showed how a visual identity could carry a career across records, films, and television appearances. Celebrity culture, with its interest in private life and public image, grew alongside these visual formats and became a commercial asset in its own right, feeding album sales, tour demand, and merchandise.
Live concerts and the streaming economy
Live performance has moved from a promotional add-on to the main income source for many established artists. In a 2018 survey of top earners, an average of 80 percent of revenue came from touring, 8 percent from streaming, and the rest from sales and publishing. Streaming payouts to artists are at a significantly lower rate than was the case for physical sales and downloads, which is one reason touring has become so important. Taylor Swift topped that list with $99.6 million, and 91% of that total came from touring. Bruce Springsteen earned 96% of his revenue from touring and less than 2% from streaming.
Large stadium tours have expanded the scale of this market. Swift's stadium tour was part of a broader trend of bigger shows, which a sister publication called "The Year of the Stadium." The Eras Tour is the clearest example. Figures differ by method. Billboard reported that the tour grossed more than $2 billion and sold over 10 million tickets, with ticket sales of $2,077,618,725 and 10,168,008 tickets. Pollstar's estimate of total gross was $2.2 billion across 149 shows, which made it the highest-grossing tour of all time. Merchandise added substantially; Pollstar estimated merchandise revenue alone at about $200 million.
Concentration in the live sector is also significant. Live Nation built its dominant market share in part by buying potential competitors, particularly in markets where it wanted to expand. This gives a small number of promoters considerable leverage over ticket pricing and venue access.
Fan communities and social media
Social media platforms have become the main places where artists announce releases, share behind-the-scenes material, and maintain contact with listeners between tours. Fan communities organise around artists through official channels, fan clubs, and independent forums, and they often coordinate streaming campaigns, chart pushes, and ticket purchases. Short clips and user-made content can introduce songs to new audiences, and a viral moment can lift an older catalogue track. These dynamics make engagement a continuous task for artists and labels, not only a feature of album and tour cycles.
Law, Copyright, and Rights
Popular music is governed by a legal structure that splits a single released song into several separate property interests. The first division is between the song and the recording. A sound recording and the music, lyrics, words, or other content included in the recording are separate copyright-protected works. Each track therefore usually carries two layers of protection. The composition is the notated melody, harmony and lyrics, and the sound recording is the fixed performance, often called the "master." Ownership and licensing of the two layers are often separated. A songwriter may own the composition while a label owns the master, so a cover version requires permission for the song, and a reuse of an existing recording requires separate permission for the master. Permission to use a composition does not grant rights to use a particular sound recording.
The two rights also differ in scope. In the United States, sound recordings have no public display right, and their public performance right is limited to "digital audio transmissions," for example, digital streaming. This narrow performance right is one reason radio and streaming revenues flow differently for recordings than for compositions, which are covered by broader public performance rights.
Public performance of compositions is handled largely through collective organisations. The American Society of Composers, Authors and Publishers, founded in 1914, developed the model of the blanket licence: venues that wished to provide musical entertainment for their customers could purchase a license from ASCAP giving them the right to perform any of the works of ASCAP member songwriters in exchange for a single annual royalty payment. Fees were often calculated as a share of the venue's gross revenue. ASCAP, BMI, and SESAC are the three oldest and largest PROs in the United States. SESAC differs in structure: it is a private, for-profit organization, while ASCAP and BMI are both non-profit associations. The two largest American organisations operate under consent decrees that regulate the copyright licensing activities of ASCAP and BMI, and the U.S. Department of Justice opened a review of those decrees in 2019. Because a blanket licence covers a whole repertoire, ASCAP does not grant licenses to perform individual songs in its repertory.
Termination rights allow creators to reclaim rights they previously granted. For U.S. grants made after 1977, the principal provision is Section 203 of the Copyright Act. A songwriter/composer has the right to terminate the granted rights during a five-year period beginning 35 years after the agreement was signed. The notice must be served within a defined window before the effective date, and it cannot be waived, assigned away, or contracted around. Under the older Section 304(c), which exclusively covers musical compositions (not sound recordings) registered prior to 1978., the window opens 56 years after copyright was secured. Practitioners also note that the rule applies to recording contracts: for recordings released after 1977, the law is a section of the Copyright Act that allows recording artists to terminate their record contracts after 35 years. Termination reverses the grant, not the copyright itself. As one commentary puts it, it's usually called copyright termination, but it's not the copyrights that are being terminated, it's the grant of rights to the record company that is being terminated. The rule has high-profile examples: if a song was written in 1965, termination can be initiated 56 years later, as demonstrated by Paul McCartney's efforts to terminate Sony's rights in a list of Beatles songs.
Litigation has tested the limits of copyright and fair use in several areas. In the United States, sampling cases in the early 1990s established that using even short fragments of a recording without clearance could be infringement, a principle reinforced by later appellate rulings. Cover versions are generally permitted in the United States through a statutory mechanical licence, provided royalties are paid, while parody and transformative reuse have been tested under the fair-use doctrine, most notably in the Supreme Court's 1994 decision on a parody by 2 Live Crew. Infringement suits over melodic resemblance, such as the 2015 jury verdict in the "Blurred Lines" case, show that courts have treated the composition as the protected element even when a new recording is involved.
Contract terms between artists and companies remain a persistent source of dispute. Recording and publishing agreements have traditionally tied artists' income to royalties calculated after recoupment of advances and production costs. Some artists carry balances that remain unrecouped for decades, and termination rights have become one tool for renegotiation. Royalty rates, the treatment of streaming income, and the allocation of rights between songwriters, performers, and intellectual property owners continue to be contested in both courts and negotiations.
Social Identity, Youth, and Community
Popular music has often served as a way for listeners to define who they are, whether by age, class, race, gender, or region. Record companies and broadcasters sell music to a broad public, but the groups that adopt particular sounds and styles tend to build their own meanings around them. This is why popular genres have repeatedly become emblems of youth subcultures and generational identity. In Britain, for example, the Teddy boys of the 1950s, the mods and rockers of the 1960s, and the punks of the 1970s each attached a distinctive musical taste to a visual style, a theme later analysed in the cultural studies literature on subculture. Because the market rewards whatever attracts a specific audience, these identities have frequently been commercialised, and the same styles have been absorbed, diluted, or rejected by the people who first made them.
Race has been central to the history of popular music in the United States. Blues, jazz, and rhythm and blues emerged from African American communities, yet for decades their performers were often denied equal access to mainstream outlets. Record charts for Black music were segregated under labels such as "race records", and the industry renamed the category "rhythm and blues" in 1949. Many early rock and roll hits were recorded first by Black artists and then covered by white performers whose versions reached wider audiences; the practice of covering was a major route by which the market separated the creators of a style from its commercial beneficiaries. Singers such as jazz vocalist Billie Holiday, whose 1939 recording of "Strange Fruit" addressed lynching, showed that popular songs could carry explicit social critique, and Motown and soul later built a commercial industry around Black artists in the 1960s.
Gender and sexuality have shaped popular music in similar ways. Women such as Bessie Smith and Ma Rainey were among the most successful blues recording artists of the 1920s, while later decades saw women's roles restricted to certain positions, such as the girl groups of the early 1960s, whose songs were often written and produced by men. Gay and lesbian audiences were central to the disco and house scenes of New York and Chicago, and the dance clubs in which these styles developed were among the few public spaces where such communities could gather openly in the years around the New York Stonewall uprising of 1969. Queer and feminist artists have since used popular genres to challenge conventional ideas of gender and sexual identity, and the riot grrrl movement of the early 1990s in the Pacific Northwest brought a feminist critique into punk and indie rock. Artists from marginalised groups, including Indigenous, Latin, and Asian musicians, have often used local languages and styles within mass-market genres, making them vehicles for local identity as well as commercial success.
Popular music has also been used in social movements and political life. Folk singers such as Woody Guthrie and Pete Seeger wrote songs for labour and social causes, and in the American civil rights movement, gospel-based songs such as "We Shall Overcome" became shared anthems at demonstrations. Nina Simone's "Mississippi Goddam" (1964) and Marvin Gaye's "What's Going On" (1971) brought political protest into the mainstream chart and album market. In Britain, the Rock Against Racism campaign, founded in 1976, used concerts and music papers to oppose the far right. In Chile, the nueva canción movement linked folk music to socialist politics before the 1973 coup, and singers such as Víctor Jara were persecuted for their work. Protest songs have repeatedly raised the question of whether commercial music can effectively oppose the institutions that sell it, a question that is discussed in more detail in protest song scholarship.
Lyrics and performance have also prompted moral panics and regulation. In 1956, television broadcasts of Elvis Presley were framed so that only his upper body was shown, reflecting concern over his hip movements. The FBI investigated the 1963 hit "Louie Louie" for alleged obscenity in the mid-1960s, and in 1985 the Parents Music Resource Center, founded by a group of Washington wives led by Tipper Gore, pressed for warning labels on explicit recordings, which led to the Parental Advisory label that the recording industry adopted that year. Hearings held in the United States Senate the same year included testimony from musicians such as Frank Zappa and John Denver. In 1989, the FBI sent a letter to the group N.W.A. about the song "Fuck tha Police". Regulatory responses have varied by country: in Britain, the BBC banned Frankie Goes to Hollywood's "Relax" from daytime airplay in 1984, while in China authorities issued guidelines in 2021 restricting effeminate male performers on television. Debates over censorship, obscenity, and freedom of expression have thus tracked the changing boundaries of acceptable youth culture and public morality.
Regional and Global Popular Music
Latin America
Latin American popular music reached foreign audiences in waves, and each wave depended on a different set of intermediaries. Big-band leader Xavier Cugat and the Argentine singer Carlos Gardel helped open a path for Latin sounds to earn money in North America. Latin music began to have commercial success in North America, and the tango was already a continental phenomenon before that, shaping the development of the bolero, particularly in Mexico. The tango was an international phenomenon in Latin America and greatly affected the evolution of the bolero, particularly in Mexico.
Salsa arose from a specific migration history. After the Cuban revolution, Cuban musicians could no longer travel freely to New York, and the city's Puerto Rican musicians quickly filled the vacuum, combining Cuban-inspired Latin jazz with mambo and boogaloo. Emerging in the 1960s and 1970s, the genre drew on the Cuban son and incorporated jazz influences and elements of Afro-Caribbean rhythms. Performers such as Celia Cruz, Héctor Lavoe and Willie Colón helped carry it abroad. Latin pop of a different kind was driven by balladeers: the Spanish national Julio Iglesias laid the groundwork for the middlebrow Latin pop genre by selling millions of records of remade and original ballads across Latin America.
Brazil's bossa nova is the clearest case of a regional style becoming a global fashion. It originated in the late 1950s as a Brazilian offshoot of samba, drawing on the harmonic language of American jazz. Its audience came from the urban middle classes, whose cosmopolitan outlook was a receptive environment for new and varied influences on traditional art forms including the samba. Its international breakthrough came in 1962, when saxophonist Stan Getz and guitarist Charlie Byrd scored a worldwide hit with Antonio Carlos Jobim's "Desafinado". The follow-up was far larger: "The Girl from Ipanema," sung by Astrud Gilberto, reached No.5 in the US pop singles chart in the summer of 1964. The bossa nova boom that followed was a short-lived but influential export, drawing American jazz musicians into Brazilian repertoire.
East Asia: Mandopop, Cantopop and K-pop
Mandopop and Cantopop developed as the Mandarin- and Cantonese-language pop industries of the Chinese-speaking world, centred on Taiwan, Hong Kong and mainland China. They spread across the Chinese diaspora through records, films and television, but their industries were also shaped by censorship and by distinct regional markets, which limited their reach in the way K-pop has since achieved.
K-pop has become the most visible example of a non-Western popular music industry exporting itself as a business. The phenomenon known as hallyu, or the "Korean Wave", has boosted the country's music export value to roughly 1.8 billion U.S. dollars in 2024, according to one estimate. Music is the largest category of South Korean content exports: music made up 32.4% of South Korea's $14.91 billion in content exports in 2024. Domestic sales are substantial in their own right; in 2024, total revenue stood at the equivalent of US $1.08 billion, with US $660 million coming from digital sales and US $394 million from physical sales.
Export success has been unevenly distributed across markets. Japan was the most important export market in one period studied, followed by the United States and China. China has been an unusual case: the Chinese government imposed an import ban on pop culture products from South Korea in 2016, yet music exports from South Korea to China grew by an impressive 76.4 per cent between 2023 and 2024. Live performance has become a key component of the model. One estimate put overseas concert revenue at 588.5 billion won, constituting 47.5 percent of the overseas revenue total of the companies analysed, which indicates how touring has come to complement recorded sales. The industry is also concentrated among large agencies; the group's label's parent company, HYBE, has been the industry leader since BTS' rise to global stardom.
Africa: Highlife and Afrobeats
Highlife is the root of much contemporary West African pop. It first gained prominence in the late 19th century within the Ghanaian high society, and in its early form Ghanaian musicians wove traditional Akan music together with sounds like jazz and calypso. Colonial institutions played a part in its formation: local musicians were equipped with European instruments and trained for military bands and police orchestras. After the Second World War, highlife became even more embellished with swing and jazz elements introduced by military personnel in Ghana. The style grew rapidly across Ghana, from the 1920s to the 1960s.
Nigerian musician Fela Kuti used highlife as a foundation for Afrobeat, which was introduced in the mid-1960s. Kuti fused traditional Yoruba music with American jazz, blues, and funk, and the lyrics incorporated commentaries about political and social issues. The term Afrobeats, plural, is a later and broader category. It emerged in Nigeria and Ghana in the early 2000s and draws on highlife, dancehall, and soca. Its international visibility rose through collaboration and broadcasting: Drake's song "One Dance," which featured Nigerian singer Wizkid, topped the Billboard Hot 100 chart for 10 weeks. Television also helped; Alex Okosi launched MTV Base Africa in 2005, the first MTV-branded channel dedicated to African music. Commentators often link the Afrobeats boom to a mix of forces, including strong local scenes, diaspora audiences, increasingly direct digital distribution, playlist discovery, international collaborations, major-label investment.
Film Music and National Industries
Some of the largest popular music markets in the world are organised around national film industries rather than around the international recording business. In India, Hindi cinema, based largely in Mumbai and commonly known as Bollywood, built a model in which songs are integral to films and their soundtracks are the central commercial product. Film songs are widely performed, broadcast and sold within India, and the domestic market has long been far larger than any export market. Similar systems exist in other regional film industries across India, where film songs often hold a central place in local popular taste.
Japan offers a parallel example of a large domestic market with limited global reach. One comparative analysis notes that while J-pop maintains a robust domestic market, its global influence is comparatively limited. Across these national systems, the relationship between film, television and records has tended to be closer than in Western markets, and the export success of a national industry often depends on whether its music can travel beyond the language and media ecosystem in which it was made.
Scholarly Approaches and Critiques
Critical writing about popular music began largely with the Frankfurt School. In the 1930s and 1940s, Theodor W. Adorno treated mass-produced songs as part of the culture industry, arguing that they were produced on the same principles as other consumer goods. He saw musical mass production as still operating at a craft level rather than as a fully industrial process, a condition he thought suited the interests of large cultural businesses. In his account, standardized song hits do much of the listening for their audience. His concept of pseudo-individualization described how the surface variety of products hid this sameness, so listeners forgot that what they heard had already been pre-digested for them.
Adorno's analysis rested on a structural claim. He argued that popular songs share a core of verse, chorus and bridge, and that these parts could be exchanged between songs with little change. Genre labels such as rock, pop or rap were, in this view, cosmetic differences over a common template. Adorno also drew a firm boundary between popular and serious music, a division that drew accusations of elitism against his work. Later scholars have questioned both the sharpness of this line and the assumption that listeners are passive. The critique of the objective, text-centred approach is that it overlooks the interpretive side of how music is received.
Popular music studies as an academic field took shape in the early 1980s. The International Association for the Study of Popular Music (IASPM) grew out of a first international conference on popular music studies, held in Amsterdam in June 1981. The association was established in September 1981, with Charles Hamm and Simon Frith among its founding members. By 1988 it had members in over 30 countries. Its headquarters have been at the University of Liverpool's Institute of Popular Music since 2002. The main English-language journal of the field, Popular Music, published by Cambridge University Press, also dates from 1981; it describes itself as an international multi-disciplinary journal covering all aspects of the subject. Its scope includes all kinds of popular music, whether rap or rai, jazz or rock, from any historical era and any geographical location. The field has older outlets as well: Popular Music and Society, founded in 1971, is one example. The Journal of Popular Music Studies, published by the University of California Press, serves as the official journal of IASPM's United States branch.
The field draws on several disciplines. Cultural studies has examined how music forms social identities, class relations and resistance. Sociology has studied the music industry, audiences and the institutions that shape taste. Musicology has analysed harmony, rhythm, timbre and form, and has often had to adapt its tools to recorded and studio-made music rather than to notated scores. Ethnographic methods, including fieldwork with musicians and listeners, have made it possible to study local scenes and the ways people use music in everyday life. Discourse analysis examines how critics, journalists, fans and industry figures describe music, and how those descriptions shape reputations and meanings. A growing body of work treats recordings themselves as texts, analysing production techniques, mixing decisions and the sonic details of a track as evidence of how a song was made and how it was meant to be heard.
Across these approaches, the scholarly literature has moved away from the simple division between art and commerce that shaped the earliest criticism. Researchers now more often examine how commercial structures, technologies and audiences interact, and how popular music is produced in many national and regional settings beyond the Anglo-American core. Scholarly publishing has widened correspondingly: journals in this area accept historical, theoretical, critical, sociological and cultural approaches alike.
Debates and Open Questions
The oldest argument in popular music concerns authenticity: whether music made to sell can also be taken seriously as art. Critics have often treated commercial success as evidence of compromise, while producers, performers and fans have countered that craft, emotional directness and mass appeal are not mutually exclusive. The argument returns with each new technology, from the phonograph and radio to the internet, and it now shapes how listeners judge playlist hits, algorithmic discovery and machine-generated tracks alike.
Concerns about homogenisation focus on whether recommendation systems narrow what people hear. A 2020 study of Spotify listening found that algorithmically-driven listening through recommendations is associated with reduced consumption diversity. The same research linked broader listening with user behaviour that platforms value: controlling for activity, generalist users are up to 25 percentage points less likely to leave the platform and up to 35 percentage points more likely to become a paid subscriber. This creates a tension for market actors: the habits that sustain engagement may also reduce variety. The evidence is not uniform. Broader reviews of recommendation research report that recommendation algorithms generally seem to increase diversity and serendipity, although some studies of specific platforms, Spotify and YouTube among them, point the other way. Streaming services also combine automated suggestions with human-edited playlists, which makes it harder to attribute any narrowing to the algorithm alone.
The economics of streaming remain contested. Spotify reported that it paid out a record sum to rights holders in 2025, but how that money reaches individual musicians is highly uneven. One industry summary estimates that 80 artists worldwide earned over $10 million from Spotify in 2025; 1,500 earned over $1 million; and 13,800 earned at least $100,000. Eligibility rules add a further barrier. Spotify's minimum monetisation threshold requires tracks to hit 1,000 streams in a 12-month period to earn royalties. Currently, roughly 175 million of the 202 million tracks on the platform fall below that threshold and earn nothing. Payment models also differ: pro-rata systems spread fan payments across all streams on a platform, whereas user-centric systems such as Deezer's send money only to the artists listeners actually play. Surveys of self-releasing artists point to the same pattern. One 2026 study of European respondents found that 55% earned less than €1,000 from music in 2025. Per-stream rates quoted by industry guides vary widely, so aggregate figures should be read with care.
Generative artificial intelligence has added a new set of legal and economic questions. In June 2024 the Recording Industry Association of America brought copyright suits against two AI music generators, Suno and Udio, alleging the companies trained their AI models on copyrighted recordings without permission. The litigation has since produced licensing agreements: Universal settled with Udio in October 2025, Warner Music settled with Udio and Suno the following month, and the Sony lawsuits are ongoing. The deals generally move toward requiring licenses for the music used to train the models. Critics note that the agreements cover major-label catalogues, so independent artists whose recordings are on streaming platforms, which make up the vast majority of the music these models were trained on, have no seat at any table. In June 2026 the American Federation of Musicians filed suit against Universal and Warner, arguing that they have refused to compensate the musicians whose work is fed into AI machines for profit. Questions of authorship also remain open. Under current practice, fully AI-generated works still face human-authorship limits in copyright registration. Court timetables suggest that any US fair-use ruling may not arrive before 2027.
