Actually those songs are all winners of the Gold Prize. They'll announce the winner of the Grand Prize at the show. I hope ayaka wins. That song is one of the greatest songs released this year. I'd be fine with BoA too.
As for the new artist award, I'm all for °C-ute. I don't think Stephanie has a chance, I mean, have her singles sold over 10k?
She has a great voice, though.
