Power Jams: Songs For Running (for me, and maybe you)

I need music when I exercise. If my music dies, so does my motivation. Here are my current favorites for running to, with links to the songs if they're available.

• Jack Sparrow - The Lonely Island featuring Michael Bolton (there's some crass language, so don't listen without headphones if you're babysitting)
• Til The World Ends - Britney Spears
• Everybody (Backstreet's Back) - Backstreet Boys
• Dying Day- Brandi Carlile
• Semi-Charmed Life - Third Eye Blind
• Dancing On My Own - Robyn
• Planetary (Go!) - My Chemical Romance
• Take It Off - Ke$ha
• Lost Without Each Other - Hanson

Only a mere sampling, friends. What are your favorite songs to work out to? What am I missing out on?
