Swimmer in need of a song!

First of all, I'd like to thank everyone who helped me with my How To Swim a 100m Breaststroke thread. I read your tips and started applying them. My big meet is near and thoughts are already running through my head. I figured I'm going to spend (hopefully) about one minute and twenty seconds in the water, so enough time to play a good pump up song in my head. What I wanted to know is: Do you play a song in your heads when you swim? on race day? What is\are your favorite song(s)? Let's dance! Gal
