Any band that works with egotist Mark Ronson.
Monster is great by the way, I am sure REM don't regret that one bit.
The Beatles' Album Let It Be speeded up their break up so maybe they regreted that.
Robbie Williams should regret his entire back catalogue.
As for The Verve. I would say Urban Hymms is a great album but A Northern Soul is better and has more depth. The songs on that album are more soulful. So with that said 3rd album Urban Hymms was a come down. I home the new album is good. I always worry when bands get back together. I hope The Stone Roses never reform because it could damage what they did.
