I don't hate rap. I love all music, everying from classial, bluegrass and eveything in between, it's about expression. I don't base my oppinion on the music alone, but I do have some problems with the lyrics. But then again that is my oppinion.
I prefer southern, classic rock and blues, which my 17 yold son laughs at. But when I asked him about the attraction of RAP he had only one thing to say. "It has flow" I reminded him that the toliet has flow also, but that does not mean I want to listen to it! He does not discuss music with me anymore :)
