Definitely get some RATM mixed in there. I like Bulls on Parade, Killing in the Name of, How I Could Just Kill a Man, etc.

Also, have you ever heard of Lil' Wyte? He's got some really good flows that pump me up. Crash da Club namely.. gets me everytime. Get some Three Six Mafia, too. Most of their songs (not the newer shit... some of that stuff is whack) are about "bustin heads" and shit.
