Work out mixes

I'm not sure if this has been done, although I'm sure it has, but I didn't take time to look through all of the posts. Either way, just curious as to what everyone listens to while working out? I lean towards a heavy dose of hard rock with a little rap thrown in here and there while doing cardio and weight lifting. If it's boxing, then it's all Five Finger Death Punch, always seems appropriate. Share your play lists people!
