^ start with her newest album, it's her most balanced album. I usually have a few songs I loathe on her albums, but aside from Happy Go Round, RokuNei is pretty solid! My personal fave is ULTIMATE DIAMOND though.
The close up promo shot is *adorable*. I'm not too fond of the covers, there's something awkward in the pose/expression. She looks so gooood in that outfit too, shame.
