The Veronicas voices just bother me. I'd rather hear someone grinding glass in their teeth. I don't mean it as an insult, because they've received some rave reviews from critics, but their voices are just so whiny and immature. The "go crazy from the moment I met you" part of "Untouched" is so unbearably cheesy.
The Veronicas have such a beautiful voice and they can TRULY sing. Unlike Katy with her whinny voice! they both voices own you and everyone elses faves.
