I like the remix of the cell theme, it kicks ass.
I use alot of stuff, usually heavy metal, Ozzy (Bark at the Moon, Over the Mountain), old school Metallica (Blitzkreig, Sleeping Peace), Megadeth (Kill the King, Into the Lungs of Hell), Godsmack (I Stand Alone, Awake), Pantera (Mouth for War, Live Through Me (Hell's Wrath)), etcetera.
