That's a hard one, it's probably one that none of us know about, but if you want to know which band that is or was at least moderately popular is definitely bad, well, I honestly don't know. Linkin Park? I never liked them and genuinely think their sound was more noise than music. I know shit about music so I'm the least qualified to make such a statement, though.
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
