i started being a fan since 2004..so I'm not really familiar with her old works..but i do sometimes listen to the old works, but still I'm not really interested with most of them...except the ones she sang again during the recent concert tours..I kinda like it..but not as much as with the new works..
my favorite albums ever since 2004, are MY STORY, then GUILTY and now Rock 'n' Roll Circus~ there after and before all those 3 albums are somehow, just a so-so album for me..not really spectacular but i don't hate them either..i still enjoy it

from all those 3, my most favorite is absolutely Rock 'n' Roll Circus, I've kept on listening to the album over n over again til now..then also MOON with blossom, specially blossom, i really love this song so much..it really feels nostalgic like her old works (I don't know why still got some ppl not really like it since it really has the old works-feeling but in a better music n vocal)
so in consclusion, ayu's music has not yet gown down hill..it's like up and down~
