If you browse YouTube for video game music you've probably stumbled upon Smooth McGroove. In fact, our own Sean Cahill did an interview with him a while back. Well, Smooth has released his latest track, this time tackling the Overworld Theme from Super Mario Bros. 2. Say what you will about the game (some like to call it the black sheep of the series), I really enjoy the game and this is a really well done acapella of the Overworld Theme.
