Nestled deep in Jacques Attali's brilliant multi-disciplinary analysis of sound in human society, 'Noise - the political economy of music', i found this,

Inevitably, the statistical evaluation of the quantity of the representation will be adopted. The usage of music will be evaluated exclusively by polls determining the quantity of the music broadcast. Musicians will be renumerated according to statistical keys and treated as producers of a stockpile of undifferentiated raw material. This shift relates to a statistical reality: the disappearance of use-value in mass production and the final triumph of exchange-value.

- Jacques Attali, 'Noise', 1977

Attali's fourth stage (after sacrifice, representation and repetition) is composition, in which he puts his money on technology liberating the music makers from the aforementioned scenario.

If you haven't been exposed to Attali's oft-quoted work, try this for a provocative hypothesis,

Music is prophecy. Its styles and economic organization are ahead of the rest of society because it explores, much faster than material reality can, the entire range of possibilities in a given code.

Skim an overview of 'Noise', read an interview with Attali by a lecturer at LCC ( where he shows his broadly optimistic view on technology in the culture industry) and finally peruse his snazzy website.
