Now, since we heard the albums tracks, I can say this is really refreshing from Ayu's previous albums.
The musical styling is really different.
Here's my reactions to the samples even though the quality is so horrid.
Spoiler:
01. Bridge to the sky
-
WOAH! It really takes me to the sky! SERIOUSLY!
A very good Startin' tune for NEXT LEVEL and Ayu's vocals are amazing!
02. NEXT LEVEL
-
This is interesting, a descendant of Bridge to the sky intro! 
03. Disco-munication
- A very dancy intro for the dance tracks ahead!
04. EnergizE
-
It reminds me of Maaya Sakamoto's High Touch and its really cathcy and fun and Ayu uses Englsh again!
05. Sparkle 
06. rollin'
-
KEEP ROLLIN'! ROLLIN'! ROLLIN'! ROLLIN'! WHAT?!? j/k
Another dancy eletronica-rock! GREAT!
07. GREEN
08. Load of The SHUGYO
-
Is this Mortal Kombat theme?!? OMG!
J/K! XD
I like the rock elements on this interlude!
09. identity
-
A dance rock track!
Somewhat it reminds me of my name's WOMAN meets In The Corner.
10. Rule
11. LOVE 'n' HATE
- A R&B dance track!
12. Pieces of SEVEN
-
Hmmmm... it sounds like Neverending Dream or something....
13. Days
14. Curtain call
-
Oh My Gosh... this track makes me cry... seriously.... a touching album ending ballad.
The Piano makes a dramatic atmosphere and Ayu's vocals was so... amazing...
Curtain call is stunningly beautiful!
[EDIT] YAY! for I Am... initiate!
