Modern music, at least the mass media music is an all-out assault on one's ears. If you look a little deeper, you run into bands like Manowar, Sabaton, and Steely Dan. They are pretty good, and do not encourage bad behavior in children. Indeed, songs like "Father" by Manowar encourage good behavior. If that doesn't sell you, how about the fact that one can simply turn the music off?
This is worse than the "D&D is Satanic" scare in the 80's. Where are the Cheetos?
