I have a very eclectic iPod. So I've got my cardio people - so it's anything from Beyonce to some Jay-Z to Janelle Monae, her song 'Tightrope,' that's a good cardio song. And then I've got Sting. I've got Mary J. Blige. I've got The Beatles. I've got Michael Jackson. I try to pick the songs that I personally love.
