Not to be mean or anything, but if you don't want to hear music, why bother responding to the thread?
I seriously doubt PD are going to be all "Wow, there are a bunch of people who don't wana hear music while they're racing!" then someone else at PD is gona be "Well, they can turn it off if they want to." Then the other guy is gona be like, "No no, these people are right, you shouldn't have any kind of music while you're racing, get rid of it!" and then... well, you get the point.
Anyhow, I dunno where you come from, but where I'm from your speed coincides roughly with the decibel output level of your stereo.
