She sang...Powder Snow... *melts*
I love that song!
And you can definitely tell how much her voice has matured from "A Song For XX" era to now!
Though we've all noticed a long time before that! But when you're comparing the two "Powder Snow"s...
She also sang "In the Corner"! About time, I've been dying to hear her sing that live! Yay yay, Ayu-Chan~~
