Workout Playlist

I go to the gym at least four days a week and always listen to music while I work out on my own (I go to group exercise classes a few times a week as well). Naturally my workout playlists get old after about two weeks, so I'm constantly removing and adding songs. Below is my current playlist {click to enlarge}. While it is certainly not all appropriate, it does keep me motivated! I am always looking for new workout music, so I would love to hear what's on your list. Please share in the comments!
