Worst Rock Band Ever !!!!

Who was/is the worst?
I wholeheartedly agree that The Black Crows are one of the worst rock bands. Seeing the great Jimmy Page associate with them makes sick. I don't know which is worse, Jimmy Page and The Black Crows, Jimmy Page and Puff Daddy, or Coverdale/Page. Hey, here's an idea! How about Led Zep and Page!!
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?
