What's so great about Justin Bieber?

[chato02]

I'm not asking in a mean way, i just want to understand why his name is always trending on twitter.
Also please give me more of an answer than "Cuz he's cute" or "Cuz he's awesome".
I want an actual reason, not just the fans squealing and moaning. I get that you like/dislike him, i just want to know why.
Here's the thing, i don't want to hate on him cuz i don't really know anything about him. And yes, thanks to his fans i do tend to get annoyed when i hear his name or his music. Also i feel that the radio and tv stations are over doing it. So for the moment i dislike him because of his fans, but i'm willing to be open minded because he's just a kid with a bunch of psychos ruining his cred...
