Saying a band sucks because you dont like their music is childish. I am not a music snob, but i do know, study and play music.
Nickleback is geard toward the Teenage crowd, not you or me. I have no problem with them, like or dislike.
If you dont like there music dont listen to it. No need to complain about it and say they are the worst band ever. Trust me they are far from it.
