User-generated content - the future of audio

An excellent text by Matthew Ball about the connection between technology and music, how the development of tech has changed or steered the way through the future of music. He predicts that the next big step in the development of technology and music will be based on user-generated content, somebody just has to find the right model. His argument is that "almost all new music today, with exception of indie rock, is 'all digital' and thus fully separable by instrument, beat, vocals, etc. In many cases, a hit track is made up of numerous samples, beats, and sounds that come from a patchwork of creators", so everything is already there, except the model.
