BOB LIKES A BAND CALLED GREENDAY. THEY ...
CoF suck! They are false black metal. Pick up a Darkthrone CD and repent your stupidity. System of a Down are a cop of Rage Against the Machine (a shit copy at that), Slipknot are completely untalented as are Disturbed. I aven't heard Kottonmoth Kings so I will not comment on them and I may look them up.
Good bands:-
Dream Theater
Opeth
Symphony X
Evergrey
