Check out Girl Talk, biomedical engineer by day completely crazy musician by night. (He actually quit his job recently after his third album blew up.) Anyway, the legality of his music is questionable. He takes mash-up to a whole other level. Mash-up proabably isn’t even a good name for it anymore. I wish our copyright laws weren’t so restrictive.
