Whenever I see Ayu albums enter top 10 positions I get excited and then it always turns out to be because of some kind of discount.
It looks like Ayu is getting harder to defend as her weaknesses keep getting highlighted lately.
But I don't think it is good to dwell on one bad performance. We shouldn't count Ayu out because she could deliver an amazing vocal performance months from now because that is how she is. Always inconsistent. Going from good to bad, bad to good. It's just got to be her hearing. It must be worse than she lets on. I think it has become more than clear over the past few years that Ayu can't control her singing. That seems to be the best explanation. She can speak fine but when she needs to sing varying intricate notes, she just can't be accurate enough. She just can't help it. So she just tries her best.
