WORST musical personalities ever!

So, following up on the amusing thread concerning Portishead's very own Geoff Barrows ranting it up on Myspace, I think it's time to let the masses voice their opinions in the category worst musical personalities. Losers, misfits, idiots, or simply extreme eccentrics all go as one here.

My nomination goes to Smashing Pumpkin frontman Billy Corgan. After ditching this great band to form his less great follow-up group Zwan, which he in turn crashed burning in a rage of misguided ego. He's been most of his time since blaming Zwan for the state of his flagging carr?er.

So, who else?
