What's the question? Good music to play games to?
If that's the case, my iTunes has a healthy mix of Rancid, Op Ivy, Distillers, Cake, Tool, Soundgarden, Smashing Pumpkins, The Mars Volta, The Yeah Yeah Yeahs, Handsome Boy Modeling School, Wyclef, A Tribe Called Quest, The Roots, Mos Def, Godsmack, Metallica, Ian Moore, and Rilo Kiley (to reset the pallet, of course).
