Worst Rock Band Ever !!!!

Who was/is the worst?
All 70's bands that wore cape's like Styx, Yes, etc.., but you have to consider bands like Boston and Journey with those profound lyric's like "Are you hot Mama? you look that way to me"
Any so called Rock band today! Rock music today sounds like there in pain. Rock died when John did!
A little off track, but the worst album by a once great band has to be the latest by Crosby,Stills Nash and Young. What were they thinking?
I'd say Oasis. 30 years after the Beatles they still don't know how to make their own music.
