I wish she would work with Yukio Nagoshi more, Yasei no Doumei is easily her best track in ages and it reminds me quite a lot of Mellow from
ZCS.
Fun fact: He arranged Yokyo from
Sanmon Gossip and has also worked with Chara, ACO and UA.
Saihate ga Mitai is a treat, too. I know Bjork comparisons are tired and all, but as others have said, the arrangement is reminiscent of her rendition of Like Someone in Love.
The baby-voice vocals on Shoujo Robot are a crime and Saito Neko unsurprisingly butchered Usurahi Shinjuu and Oishii Kisetsu. Other than that, the covers don't stray drastically from their original arrangements. There's not much to say.
