From the preview this seems to be a promising number! I hope she's releasing this as a single before a wonderful new album
The only thing I have reservations for is that she's using her
Ivy voice here. I don't know how to describe it. It sounds raw at times, e.g. "Tatta hitotsuu moshi negai g
aaaa" - in the bold part she sounds...struggling to be on pitch. And I noticed this repeated several times in the preview as well. Raw, is probably a good way to describe it. It would be good if she touches up on her voice for the final mix but somehow I have a feeling that that's not gonna happen :s (but it happened before in her old songs, i.e. STEP you, About You, GREEN, Moments - they're all different from their CM versions)
