Eminem - Without Me (acapella), slowed waaaaay down to 80 bpm, small timing corrections, reverb.
Coolio - Gangsta's Paradise (instrumental), chopped and rearranged, stereo widened
Just for fun, based on Satis5d's idea to use Gangta's Paradise, thanks. A long one, because of the rap.
Hahahahaha! I was actually playing around with this instrumental A few days ago after bumping into it. I like the way you slowed it WAAAAY down. It gives it A whole new feel. Nice work.
