I cant stand rap myself, but I would never try to force my kid to like what I like. I remember when I was a kid and hated what my parents liked. fortunately my 13 yr old boy listens mostly to rock, alternative, and some little classic rock. it seems to me that if you attempt to regulate what they listen to, they will simply listen to what they want when they are away from you, so you don't know about it. by allowing kids to be themselves in front of you instead of doing things behind your back, you help build character and development.
