I like me some heavy metal. I have an odd mash up of it though. lol
On any given day I'll throw in some Godsmack, Ensiferum, Rammstein, Metallica (their real metal from BEFORE the black album!), Megadeth (Endgame fucking rocks), Demon Hunter, Anthrax, Five Finger Death Punch, Slipknot, Tool and Throwdown.
I'll also throw in some Black Sabbath and other classic rock from time to time. If I'm feeling particularly cheesy I'll listen to Dragonforce, Hammerfall, Manowar, etc.
