Sorry to be offtopic and trite, but I find it hilarious as I'm reading this thread I'm also consuming a store-bought baguette and a few red apples. It seems as though bland surrounds Nickelback.
To be honest, I've listened and enjoyed some of their radio hits in the past, but I don't actively seek them out; they are not bad, but are quite generic. It's not bad to consume saltine crackers or baguettes every once in a while, but they won't have you salivating at the thought of eating/listening. I'd say this describes most of Nickelback's audience I've encountered thus far.
