...well, she's out of the top ten?
Personally I can never hate any artist, because hate seems to imply a personal level for me. Unless they committed a really bad crime, like mass murder or something...
I can see hating a song, and not liking someone's voice. And I can see fans being disappointed by a release, I know I have done my share of complaining. But I think if you don't like the artist/actor/model/whatever in the first place, why waste time?
Kinda like that time when a DBSK anti-fan tried to poison Yuhno...really makes me wonder
