I'm not even an old fan of Ayu. I've been a fan since 2005 or 2006-ish. But, I first heard Dearest by Ayu. (My sister used to watch InuYasha, so I heard the songs after the show and liked some of them. Especially Dearest ^_^) Anyway, I looked Ayu songs up and got old ones. The first songs I heard after Dearest were SEASONS, Trust, Depend on you, Real me, End of the World, POWDER SNOW, Fly high, evolution, Boys & Girls, etc... I think the reason I liked her was her sound. Some of her old stuff sounds so different from music you normally hear on the radio.

Anyway, to get to the point of the post, I really only listen to her old stuff now. Before, I would buy her new CDs and like them, and I kind of forgot about her old songs. After a while, I strated to listen to I am..., Duty, LOVEppears, and I really enjoyed it more than her new music.

I think after being in the business for so long, there are less ideas to use for lyrics, composing, instruments, etc. Maybe that's why some of Ayu's newer songs don't make an impact on people.

To answer the question, there are only a few new Ayu songs to be considered "timeless". Mirrorcle World for sure, Moments, alterna, and some others too. The songs imo just don't sound original anymore. It sounds as if I've heard them before. For instance, I love the song Duty. It is so interesting and different sounding. The lyrics are also very powerful.

I hope Ayu starts releasing things like I am... and Duty again. In my opinion, they are two of her best albums. But for now, some of her music is just... I don't want to say it, but boring.
