I don't know why, but the instruments (especially the bass) almost always stop for no reason and then go out of synch (even though the code is correct). If you can find a way to fix it, feel free to remix it. As of the upload date I seem to have fixed this problem. However, if it doesn't work for you then feel free to remix, etc. I made this like six months ago when I was bored during class. --- Song is "Smoke on the Water" by Deep Purple. I assume that they or their label own the rights to the song.
