What music do you run to?

There was just a question that asked what music you like to dance to and it made me think of the music that I like to run to. If it is something really rockin I have more energy. I like CCR, Rolling Stones, a little CC Music Factory, Journey, Bruce Springsteen, Brian Adams. The list goes on and on. I only allow myself to listen to this stuff, I keep it on an iPod shuffle, when I run so it is a little extra incentive to get out the door.
