Billy Corgan has single-handedly ruined what was a good band (The Smashing Pumpkins) with his complete inability to sing, dance, write worthwhile poetry or be a decent front-man in any shape or form.

It's not that he can't play guitar or write music well, it's just that he sabotages any glimmer of talent that he may have had by opening his mouth in front of a microphone. Only then do you realise that there's a stoned, wounded and mentally challenged cat screaming to get out.
