I'm glad she sang A Song for xx, BRILLANTE and of course, ever free! Finally!
I agree that Diary is unnecessary, especially when it's your 20th anniversary.

but yeah, it's a space that another hit from the past should have taken, even though ayu wrote it.
ayu sang SEASONS and SURREAL on CDTV live. She was really good in SEASONS!
You could actually see how much she wanted to sing it well.
