To be fair, the worst band in the world is probably actually Anal Cunt's early material, when they were still sticking with 'no titles, no song structure, no riffs, no rhythm'. Just hideous dischordant a-musical noise. Unfortunately, that's really avant-garde, and people started digging them, so they started going for hyper-offensive lyrics and such. Problem is, they just ended up as a fucking awesome band. It's hilarious that people take songs like 'I Sent Concentration Camp Footage to America's Funniest Home Videos'* and 'The Internet is Gay' seriously. Well, at least 'I'm Glad Jazz Fags Don't Like Us Anymore'.
