Most CD players will skip the data track, which is always #1, and play the second track as track 1. But there are some players that will try to play the data track, and either make no noise, or tons of racket, depending on how it is. (older will make noise, usually)
Hmm, I didn't have any problems with the music playing from the CD. I turned it off after some time, though, because I usually listen to the radio when at the computer.
