Sorry. People who know they're being monitored behave differently. My experience is that music blaring is associated with erratic and dangerous driving. I suppose low volume music which does not hinder hearing the traffic and things around them that need a response from the driver MIGHT be OK. But high volume isn't one of the parameters described in the base report.
I'm positive that the people with blaring music and/or headphones have no idea of the havoc they cause on the road. So the self reporting would not even realize they had a problem.
