Subsidizing Music (Score 3)

I just finished looking over many of the details of how Prince disseminates his music now. Its very similar to what Stephen King is doing with his new e-Book. The basic idea is, 'If you all want my book to freely use and trade etc, at least X amount of you have to buy it'. Or, to subsidize it, for it to be free to everyone else. I think this is Exactly the model the Internet should adopt to compensate artists. Its very elegant.
