zazah,
I was skeptical about 6+ minutes, but actually listens very well. Nice progression and arrangement! From all modern, (traditional influenced Pop/Rock) Japanese tunes I have heard, this one is among most interesting ones to my taste. Good mix. Robo UTAU voice seems to be well articulated and gives a very good musical sense of where you are going with melody and intonation, but I wish one day you record a live singer on this smile Thank you for sharing.

Misha.
