Music(/information) = public property? (Score 2, Interesting)

Instead of getting nowhere by going through the same discussion (that is, whether filesharing is legal, illegal or something between) again and again, I think we should bring up the question if information should be public property; this seems pretty much the debate in the Internet age. RMS has had some arguments for free software in his essay. The text may (!!) make some sense when you replace the word 'software' with 'music' (though a piece of music isn't something that evolves continuously). Of course the music creators want credit for their work, so what about a Creative Commons license for every piece of music? Why couldn't it work?
