I don't get it. He's a performer, too, right? Doesn't he understand that performers get tired, sick, stressed out, and have bad days? Generally if Ayu's vocal performance is bad, she's got a legitimate reason for it (i.e. her ear infection, the flu, strained voice from singing too much). Give the girl a break already. Plus, Ayu's songs are hard to sing. I'd like to see him get up there and do any better. He's probably just jealous because he's not as popular as she is anymore.
