Yea, her singing has definitely been affected. It's already quite hard to hear yourself in that loud music and everything, and now, with one ear gone, she really needs her other ear a lot to help her find the right pitch and hear herself. I hope she doesn't strain it.
On the bright side, her vocals have become stronger.
(actually MW is tough to sing...and i tried the yea yea yea and woah woahs...its hard to have it perfectly like how the CD has it especially when her voice is bold and strong)
Her fashion is really good for me HAHA. Every single is a new style so thats really good. Not called Ayu for nothing.
