"nickleback" is actually a canadian word; it translates directly into "talentless hack".
i can't say anything that hasn't already been said, but i can reiterate all the important things.
-all they're songs are the same. they don't sound they same, they are the same. it has been proven.
-they're music sucks.
-the fact that they are popular in the main stream just adds insult to injury. not only does the world really like a band, they really like a terrible band. and the rest of us have to associate with that population by proxy, which makes us look terrible as well. nickleback is making everyone look bad; some by choice, some by association. that's not fair to anyone.
-nickelback is like that kid in high school who has a strong, edgy, outer appearance. the problem is that it's literally not fooling anyone (well, any reasonable individual at least). you know that if kicked in the shins, said individual would keel over and give us his best pro soccer impersonation, make all sort of empty threats, crying, and possibly messing himself just to really sell it. many of the nickleback songs i have been forced to listen to are exactly this: a facade. "rock star" is the only one i can think of off the top of my head.
-to top it off, legitimately good music will get passed up by millions because they are so engrossed with this (and other) meritocracy; i think that's a pain we can all share.
