Let the child make own choice of the nature of music, musical groups, and even the volume of execution. Remember: your parents didn't like the Beatles. You can intervene if you will disturb the contents of the song, incitement to suicide, perverse sex, violence. The child listens that somehow affects him or reciprocate his feelings, In any case, the addiction to destructive issues is a bad sign. Talk to your child, find out why this music attracts him. Hopefully, you will be able to convince him to give up these addictions, and if you don't have to ban them.

Respect for others implies that you do not cause them that it would be unpleasant to you. If the teenager turns up the volume (or watch) that the music interferes with the other, it's bad.
