What's your personal theme song in life?

When you step up to the plate like big-leaguers, what do you hear playing over the PA system?

What one song gets you're blood-pumping to the point that you feel like you could take on The Hulk?

Personally, mine's Lust for life, the Iggy Pop version. I hear the intro to that song and I just wanna go out and kick some ass!
