I took against them initially, because they stole Tori Alamaze's song and killed her career and couldn't even sing it as well as she did. However I have a theory that because Pussycat Dolls themselves are such soulless sex-automatons, the more generic the song the better they are to it - ie they fall flat on 'Don't Cha', which is inventive and subtle, but ride the formulaic hott beatz of 'Buttonz' triumphantly.
