Nickelback has been known to have a split audience, listeners that hate them and others who really love them. For whatever reason, Nickelback has been one of those bands that people hate on other people for liking. As Bobby Bones put it people "fake hate" on Nickelback because it's the cool thing to do, and a similar thing has been happening with Creed. Bobby is a huge fan of both of the bands so he doesn't understand why people "fake hate" on two really good bands.
Eddie is one of those people that isn't a fan of either of the bands. He didn't have much of a good reason either, he just admitted that he didn't like their music.
