i heard all normal Ayu albums, not remixes -_-
L'arc-en-ciel, HYDE, Girugamesh, D'espairsRay, Abingdon boys School... may be anything else, don't remember.
I heard all songs by Coaltar of deepers, but don't like it so much.

WHAT?????????
you've heard all songs by Dream.. OMG.. I'm searching all of their songs..

Ayu
Hikki
Ai Otsuka
I'm not sure if I've heard all of Kuu's songs or not
And I used to be completely up-to-date on BOA, but after she released the Face I became completely uninterested. I'm sad her music went in that direction. :(
