I created this acapella following this tutorial: http://www.halo3forum.com/music/164655-how-create-cpu-acapellas-full-tutorial.html

I decided to follow the original song closely, because it is just easier that way.  I should probably make the kicks more prominent, and add some more interesting drum patterns with open hi-hat, but seeing as how it is already two days late I’ll take it for what it is. I’ll probably use the acapella for a mashup if I get around to it. Enjoy!
