The revelation is....

A major website update.

They revealed the first tracks on both albums:

Track one on AMARANTHUS: "WE ARE BORN"

Lyrics: Fujibayashi Shouko (worked on lyrics for songs from One Piece and Kamen Rider)
Composition and Arrangement: tatsuo

Track one on Hakkin no Yoake: "Tougenkyou" (Paradise on Earth)

Lyrics: Mori Yuriko
Composition and Arrangement: NARASAKI

Next two tracks revealed. Guess they'll release them daily.

AMARANTHUS Track 2: Monokuro Dessan/Dessin (Monokuro means Monochrome and Dessan probably comes from the French word "dessin" which means "drawing". The dictionary I have says it is like a rough sketch of something, but it's hard to translate it. Monochrome Drawing/Rough Sketch? Not sure.)

Lyrics and Composition: CLEVY (C&K)
Arrangement: Komatsu Kazuya

Hakkin no Yoake Track 2: Hakkin no Yoake (Dawn of Platinum)

Lyrics: Maeda Takahiro
Composition and Arrangement: Yokoyama Masaru

Looks like there's gonna be a lot of new songs. Which is great...but it's also a lot of work, preparing a tour made up of mostly new songs, while also promoting it, and all that added to their regular workload.

AMARANTHUS Track 4: "Buryoutougen Nakayoshi Monogatari" (The Story of the Friendly Utopia, I think.)
Lyrics and Composition: Hyadain
Arrangement: Hashimoto Yukari

Hakkin no Yoake Track 4 (listed as another #3 on the site, but probably an error): "Yume no Ukiyo ni Saitemina"

So am I! Hopefully this isn't his only track across these albums.

AMARANTHUS Track 5: "Katte ni Kimi ni" (Involuntarily You?)
Lyrics: Momoiro Clover Z and NAGAE
Composition and Arrangement: Oosumi Tomotaka

Hakkin no Yoake Track 5: "ROCK THE BOAT"
(It's not a cover of the old American song, from the looks of things, despite collaboration with overseas producers.)
Lyrics: Iwasato Yuuho
Composition and Arrangement: Nicole Morier and Greg Kurstin

^ Yeah, song titles and the writing teams are sort of interesting, but they don't really tell you that much. I'm dying to hear some more actual music samples :((

That's a pretty interesting production team on ROCK THE BOAT though. Both of those people seem to have produced some pretty major Western pop songs, so it should be quite different from the rest of the album. From Nicole Morier's solo work, I'd guess it will be sort of like a Perfume track but more indie-pop inspired.

That's also cool that Momoclo participated in the lyrics on the other song. I guess they really might be planning to eventually evolve into artists in their own right.

AMARANTHUS Track 7: "Saboten to Ribbon" (Cactus and Ribbon. What could that mean? Wani to Shampoo-esque title, but will it live up to it?)
Lyrics: Tadano Matsumi
Composition and Arrangement: Satoru Kousaki

Hakkin no Yoake Track 7: "Country Rose/Roads ~Toki no Tabibito/Ryoujin~" (Traveller[s] of Time. Both readings can be used for the words, and it does not specify which one.)
Lyrics, Composition and Arrangement: NAOTO (from the band ORANGE RANGE)

It can also be read as Roads too. But again, no specification. Should be cleared up in the near future.

I am a big fan of Greg Kurstin’s work, especially his productions for Lily Allen, Kylie and Sia, so I am very glad to hear that one of his productions will be on MCZ’s album.

Info below might be spoilers -- also, I could be completely off, but figured I would point it out.
