So I listened to the full album and...
I'm so happy that this album meet my expectation, even though not 100%.
Basically people at cpme.net complains that, most of the songs in this album sounds like FJ or FJ YUUKA songs, like I said before, maybe they prefer the heavenly sounds of Kalafina, rather than the organic or humanly music in this album.
But, I still enjoy the album a lot
