Sam B - Who Do You Voodoo, Bitch

This was the theme song of a game called Dead Island.  It was a reasonably good game, but this song was absolutely fantastic.

You were actually able to play as the mythical rapper Sam B and he was a pretty good choice.  I never finished the game unfortunately, but that's not the point.  The point is this is the first rap song I ever liked, and it sent me down the path to all kinds of rap stuff.
