At first, when the tracklist came out I thought for sure insomnia would be an interlude. This title remebers me Marionette prelude. So for me isn't a suprise at all
.
Anyway, I won't listen those chaku uta previews because I hated RnRC previews and I still don't like much of the album. I prefer listen to full album in decent quality.
Also I don't understand why everbody's seems to hate TK. I think he composed some of the best ayu songs ever and I'm very happy she isn't using the same composers. So TK gives a breath of fresh air for ayu comparing to the releases of last year.
