It's not that Nickelback doesn't have bad lyrics. It's that it feels like hearing hundreds of people screaming their heads off about a C-rated romantic comedy, having never seen an F. Until I moved to a part of the country that wasn't familiar with post-grunge, I was used to people either liking Nickelback, or giving it that C-rated review -- "meh" -- or outright saying they weren't their favorite thing. Not exaggerated, fake-murderous rage.
Alternately -- and this might not be you, so I'm just saying in general -- it seems like people think they're cooler for violently hating Nickelback. Like it's a sweet new trend that will make more people like them.
