What's your ONE song?

You know what I'm talking about. That one song that comes up in the middle of your playlist and suddenly your workout is kicked into maximum overdrive and you're trying not to dance through the gym to the next piece of equipment. People might stare, but they know what it's like.

Post the one song that pumps you up -every- time.
