I have a friend who has this problem, but her mom is pretty hard on her. She has some tattoos and her mom tells her that nobody is ever going to marry her if she doesn't accept that she's black.
It's rough because there's so many race stereotypes out there, and people expect you to listen to "black" music, which is just silly.
I think it's great that you've been able to expand your mind and find new music rather than being brainwashed by MTV into listening to what you "should" listen to. So in short, no there's nothing wrong with you. Every person on this earth is unique and beautiful and interesting, so don't let anybody tell you what you should or shouldn't do.
