First of all amazing graphics. Love Katy topping both the charts. SO MANY great artists/videos that I don't know where to start. Love the majority of them!
I do not like Justin Bieber at all. He has one cool song and one acceptable song but that's it. Nevertheless, Justin had quite a year, he was everywhere, even with half of the world hating on him the kid didn't stop making what he likes to do, music! That's something really cool and he surely defines 2010 along with some other artists, he was one of this year revelation, congrats Justin!
and so is the teenage dream video
Glee
