An article in the New Yorker (March 26, 2012) describes the role of producers (who generate chord progressions, beats and computerized synths), “top-line” writers (who generate melodies, lyrics and hooks to attract listeners) – who then market to performers to add their voice and market. The market for producers and top-line writers is concentrated, thus impacting the similarity of music across performers. The producers and top-lie writer teams market their song structure to performers and pick the ones most likely to generate hits. The performer may record their voice anywhere, and the voice would be combined with the chords and edited to generate the song. In other words, the song is an assembly of disparate performers working at spatially distributed locations and time points. Given such a supply chain for song creation, should one expect similarity in the output across performers or would the need to be successful generate a portfolio of song types ? Should one expect “trends”, as in fashion, that would rely on specific tune types generated by producers ? Will such platform based music result in a few performers generating the bulk of the hits and crowding out new performers ?
