Who are the singers and Bands that You don't like?

Oh, poor Nickelback, being compared with Bieber. LOL
So, i don't like Rap songs, everytime they come in the radio station i change. I can't stand repetitive stuff! I don't like some of the pop music too, but I'm not a hater. I used to like One Direction. They have such a great vocal harmony group! What do you think about them? Are they in your black list?
