In the Forum - Do you listen to music when you exercise?

This week, I'm thinking about music and exercise. One reason is because the batteries on my MP3 player died at the gym yesterday. Is there anything more disastrous? I was so devastated, I almost left...almost. The rest of my workout was spectacularly draining and I realized how much music keeps me going.
