WTH I would never say a death metal band should die just because I like dance music. :/
ANYWAY I really don't know what people are talking about when they say he can't sing... He sings live very well. And I mean VERY. He's also a very talented dancer, and I was very pleased with his minor acting in that skit on SNL with Tina Fey. I can understand if you personally just don't like his music due to your own tastes, but there is no reason to say he can't sing/has no talent when he clearly does. There's even less reason to say you don't like HIM because honestly, has anyone here personally interacted with the guy?
He sings exactly like the CD, dances better than most young stars (keyword: YOUNG), and as for a "girl voice," he'll grow out of it. Damn, you act like you've never had a high-pitched girl's voice. o_O
Baby live, though in a lower key because his voice has changed a bit
And yes, I like Justin Bieber. Music's catchy and he's darn promising as a singer/entertainer.
