I think (miss)understood and Secret are my favorite albums right now. To the hell with Ayu's past. She had very good music, but a little repetitive to my taste. I can't never get to listen to her old music for a long time. On the other hand, (m)u and Secret are probably the ones I've listened to the most, and the singles they included were very good too.
From My Story, for example, I'd only save the ballads. And Guilty.. well, Guilty wasn't that bad, but it just seemed to me like a merge of the rejected songs for (m)u and Secret, songs that I enjoyed but not much. Also, I think she needs to come back to the three/four singles per year. 06, 07 and 08 only had two. Ok, she had the Bests, but those were not really necessary. I'm sure Ayu never agreed to put those on sale, but that's a different story.
I hope she releases more in 2009 and that she puts out a new album.
