Everybody needs a little Nickelback in their lives from time to time. They aren't really as bad as they get credit for, so in small doses they can be genuinely enjoyable. It's when the airwaves get saturated with their music is when it's no good. No music, no matter how good, is worth ruining with overplaying. That's one of the reasons I'm glad I like the music I do, I've managed to avoid it getting over exposure since my town doesn't have either a Metal radio station or a good Rap one.
