Think nobody interesting uses Creative Commons?
CC is a special license that allows anyone to download, share and mix other people's music as long as they give proper credit. Recently, Nine Inch Nails released their album under a Creative Commons license, and it has been a great success!
Good old Charles Manson of the Tate and LaBianca murders has done the same thing. His recent album, "One Mind" is licensed in a way that allows anyone to share it with others, remix it and use it for non-commercial uses. The exact legal details are here.
