I don't think there's that many people who dislike Nickelback. It just became trendy to dislike them, so people jumped on the bandwagon, regardless of whether they actually cared either way.
I tried because so many of my friends dig them. I just can't get past the songs that seem like they're written with a rhyming dictionary and they're full of teeny bopper cliches. I love the guitar tone and some of the riffs but I just can't get past those dumbass lyrics.
