I must admit I am completely convinced. Au has two types of albums: catchy ones that you forget easily, and albums that take time to get into. A ONE is definitely the latter, but I have to say this is pure Jpop gold. It's even more Jpop than most of her previous works. I love the sweet & sour atmosphere of the whole thing and for once I'm not even bothered by the ballads (maybe except Zutto...). Amazing Ayu, keep going
