Introduction: I really like this intro! It reminds me of something Matt Hill would do and I approve! Plus I think it really sets the mood for the whole album.
HUSH: Well produced song, which totally deserved to be a single. Just like in HOT HOT later she uses quite sensual, aspirating vocals in some parts. I really think in mood and style HUSH and HOT HOT work very well together, HUSH leading to HOT HOT.
Dangerous: It's a pretty complex song and I'm quite astonished Kuu composed the main parts. I don't really like her other two composed songs much. But this one works so well, spreading energy, but also has parts creating a rather dark atmosphere. I'm sold. If she creates such great songs with the help of Kenji she can go on with that!
WATCH OUT ~DNA~: The track I don't like that much, though it does work in the context of the album here. And in HQ it has some really great grungy beat going on I dig. So when listening with headphones I don't skip it because of that beat, hahaha. Like I said earlier I appreciate what she wants to do with it, also setting a bridge thematically to the next song.
ScREeaM: Musically this track is awesome, another complex song! Also like the theme of the song which climaxes in her singing "It's ok to be afraid". Too bad the chorus is such a fail lyrically.
CHANCES ALL: The song makes so much sense coming after ScREeaM, a song about fighting everyday in daily life! Here she sings about how she herself fights everyday to be happy in this world. The rainbow is present in both songs, too.

And even though it misses a proper climax I really enjoy this song. The lyrics are great, too.
Aenaku Naru Kurai nara: Her vocals compliment the classical arrangement very well in this song. And they're pretty soft as well. It just works for me.
HAIRCUT:A song with a quite advanced sound and lots of layers going on, which makes it very compelling listening to it with headphones. Her different vocal approaches from rough to soft makes it also interesting. And I like the lyrics. Overall just well produced.
Guess Who Is Back: The hardest rock song she ever did! That guitar part towards the end is love! She said that the anime team requested a "mixture rock song" from her and she immediately thought about her husband and TEEDA as it's their specialty. Well produced and unique for her discography.
HOT HOT: Unusal structure for the song and I like that. Playful lyrics, accompanied by deep, sensual vocals. And catchy. Awesome and very fitting for summer like she intended to.
Kokoro kara i love u: This ballad evokes the feeling of already knowing it. In the sense like I would feel like knowing a person forever already even though I've just met him or her. Do you know what I mean?

A comfortable feeling. Vocals are awesome here. Fits to some of the great ballads on W FACE inside being in the same style.
Work That:Some say the electronic sound is dated, but I never cared much about something sounding dated. The very cute vocals surprisingly fit the song, though I admit I had to get used to it. A combination of cute vocals and a western, "serious" sound is interesting and makes the cuteness bearable. It's also quite different for her discography.
Pin Drop: This is the biggest surprise for me! I liked the preview, but the song is so much better and evolving differently than I imagined it to be. I simply love it. The "don't give it up" background chorus and the accelerating part directly after give me goosebumps. And the tone she sings in sounds very comfortable for her. Considering it's a live performance song, I really can't wait to see her tour performance for it!
Overall an album that works and like others said bring together what she has done earlier in her career and experimented with in recent years. She definitely accomplished what she wanted to do with it, compiling the Koda Kumi sound while giving a further direction for the future.
Sound and especially also her vocals are well produced overall.
From HAIRCUT till the end it's pretty flawless to me.
