Oh wow, I have a bunch I could use. I love listening to the kind of hard rock that gets your adrenaline pumping, especially when I'm driving around, therefore a few I would use would be:
Fuel -- Metallica
Devour -- Shinedown
Got it Made -- Theory of a Deadman
However, there would be one go-to guy for theme music, and that man would be
Frank Klepacki. I absolutely LOVE his work in the Command and Conquer games and my choice for my theme music would be "Full Stop", which is part of the soundtrack for the original game. Long Live C&C!
