Lets get physical.

Yes, that was an 80's song title by OLIVIA NEWTON-JOHN. Please feel free have the song stuck in your head all day =)
My new years resolution is to work out at the gym more that I am paying for and haven't set foot in, in months. The problem is I have no work out music. I am asking for those with MP3 players, Ipods etc to recommend work-out play lists. I like peppy, preppy, poppy tyle music. So. forum, what music gets you motivated to work out?

Thanks in advance =)
