I really would prefer it if you people could just turn your music down. I don't care if you want to destroy your eardrums listening to crap. I just don't want to hear music so loud it drowns out normal conversations from people on the street.
See, the thing is, it doesn't have to be THAT loud.
All it has to be is loud enough for someone else to hear. Could be the person in the neighboring car. If we're both stopped at a light next to each other, it doesn't take a whole lot of volume for my music to be audible in your car. And that, by ASCAP's logic, is a public "performance."
And you can't tell me you've never cranked your stereo when one of your favorite songs comes on. We've all done it.
