definitely different
These songs have all been taken apart and put together entirely differently with different instruments, various samples, but no consistant vocals -- but with the "spirit" of the original songs intact (in some ways, better?). There's a lot of humor here but (IMHO) the artist really liked/understood the original songs and did great reinterpretation of them. It's certainly not for all people, though -- make sure to listen to the samples first. Thanks to emusic for making this available!
