When I lived a little further up the Valley, I often had the opportunity to hear music which I found offensive played loudly from nearby pickup trucks at stop lights.  

Had a CD done on Bagpipes of "Amazing Grace" which I turned on and turned up to drown out the music.  (Well, I did roll down all the windows of my pickup to 'share' my musical tastes with the ones who had been kind enough to share there musical tastes.)
