The video below is from Vini087z where he plays a multi-track of the Super Mario Bros theme song. If you roll over the boxes within the video, you can hear each different parts of the track (Harmony, Bass and Melody) -- this must be a new feature of Youtubes as we've never noticed anything like this before. Hey Vini087z, where's the sheet music? Don't hide it, divide it. :) Nice job with the SMB tune.
