I Need A New Playlist

Keep in mind I like cardio, specificlaly running but I'll also do the elliptical machine. I like to lift some light weights sometimes too, but I'm not big into strength training (although I should be). I tend to like to keep my workout playlists to metal - every once in awhile a pop song gets mixed in. Also, I don't want any classic glam mentioned - I own all those songs anyway and most are already on at least one of my iPods (one I use for my car, the other for training). So fire away. I'm anxious to hear what you like to listen to when working up a sweat!
