Patrick from Fall Out Boy said something about this recently, that made total sense. Nickelback has sold millions of records, sell out tours and all that, but it became "cool" to not like them. Actual Nickelback fans, who are out there buying all the albums and coppin' mad tickets are now ashamed to say that they love the group.
It goes to show you how sheep-ish music fans are. Just like cats on here, people are afraid to actually be fans of artists or groups that may not be "cool" to like. You see it on here daily, cats asking if it's "ok" to like certain artists or albums. No one has their own opinion anymore. Nickelback fans are scared to say they support them, so they run with the trend of actin' like they hate them. It's mad childish. Like whoever you like and support them.
