In regard to this discussion, I would have to say that I am more fond the the "former ayu". Reason being, I could relate to her as a whole in terms of lyrics, image, etc. Her lyrics just enamored me because she seemed so genuinely innovative in comparison with other female singers at that time. I can't properly clarify what I'm trying to say but there was much more authenticity and rawness to her and that's what attracted me to her music back then. And I agree with Yumsushi in regard to her current image. Not a fan.
And as some of you mentioned before, I incessantly find myself listening to her older discography rather than her newer material. I am still a fan of hers, its just that her music no longer gives me that sense of exhilaration as it used to. Nevertheless, I do appreciate her growth and maturity for without it she would not be who she aspired to be presently.
But hey, to each his/her own.
