I didn't listened to this album from the first song to the last but in a random order.I will comment only the new songs:
Sakura - not really my favourite but I really like her "aaaa" in the middle section
petal - haunting vibe similar to the one on GUILTY but somehow it's a lot more refreshing,I think it's a highlight on the album.One of my favourites.
Gloria - I like the circus sounds (very refreshing;reminds me of how I thought it would sound Rock'n'Roll Circus).Another good song
Bye Bye Darling - I like the energy of this song and the verses (very good to listen to it when I'm in the car or when I'm running)but it's a bit repetitive
Untitled 2 - Very emotional this song.I didn't expected to be like this but I like how it turned to be.
Glassed - love this interlude.Wish it were a full song.Bittersweet feeling
task'n'bass - I like a lot the introduction and the ending.Reminds me of Until That Day.. a bit.
I like a lot the new songs (Sakura it's a bit boring but in time you'll never know) and almost all of the songs gave me a bittersweet & healing vibe (similar to Duty & Rainbow but refreshing in it's own way).
P.s:I also noticed a change in her voice
I think it sounds better.
