Featuring Yui
Tracks :Sunday Siesta, Guitar ni Kubittake, Let's go! (Yui version)
Singer :Aki Toyosaki

My comments : Eh, I'm not such a big fan of Aki's super-uber kawaii voice. But at least hers is Kawaii in a way that is not annoying (like Rie Kugimiya). Guitar ni Kubittake is my favourite track in this album, as well, it's rock. But... She sounds a bit like she trying a bit too hard to make it rock. Sunday Siesta is a relaxing song, something you will listen to when you are on vacation in Hawaii or something. Don't really like it. Her Let's go! is not that bad, but Mio & Tsumugi's version is way above hers.


Featuring Mio
Tracks :Heart goes boom!, Hello little girl, Let's go! (Mio version)
Singer :Yoko Hikasa

My comments : My second favourite album out of all of them. This is mainly because Yoko Hikasa is the best singer out of all the girls, and her singing is actually very good. My favourite this time is the slow and tasty Hello little girl. A bit of alternative element in the beginning, and it becomes a slow, pop song with a very nice tune. Heart goes boom! is a fun and energectic rock song, which is expected. Her Let's go! is much more energectic than Yui's, but then, I think Yoko's voice is suited for this type of rock songs.


Featuring Ritsu
Tracks :Girly Storm Shissou Stick, Mezase Happy 100%↑↑↑, Let's go! (Ritsu version)
Singer :Satou Satomi

My comments: Better than I thought. Her songs are all very energectic & happy. Something good to hear in the morning. My favourite track is Girly storm Shissou Stick. The beat is fun and it's a pretty high song. I don't really like Mezase Happy 100% and her Let's go! is a bit dissapointing. I was expecting it to be more energetic... but overall, the album is still ok.


Featuring Tsumugi
Tracks :Humming bird, Dear My Keys ~kenban no Mahou~, Let's go! (Tsumugi version)
Singer :Kotobuki Minako

My comments : This is my favourite album out of all of them. Minako's voice is very comforting, a bit soft yet powerful and easy to listen to. My favourite track is Humming bird, which actually sounds so good that it can be use as a theme song for some anime or drama. The music is awesome too. Dear My Keys ~kenban no Mahou~ is also another very awesome song. The starting sounds real nice, and her voice really fits. It's very fun to listen to. Her Let's go! is surprisingly very good, she sound very good in there. And note that there is less rock element in this album.


Featuring Azusa
Tracks :Jaja Uma Way To Go, Watashi wa Watashi no Michi wo Iku, Let’s Go (Azusa Ver.)
Singer :Takatatsu Ayana

My comments :Her voice is actually half-way between Mio & Yui. Something like what you will get if you fuse Yui's & Mio's voice together. Her album is ok, I don't really like Watashi wa Watashi no Michi wo Iku. Her rapping in Jaja Uma Way To Go is cute & fun to listen to, but it's not something I will listen for a long time. My favourite track here this time is actually her Let's go!. It sounds great, because of her voice.

Overall rankings:
Favourite :Tsumugi > Mio > Ritsu > Yui > Azusa
Let's go! versions (lol) :Mio > Tsumugi > Azusa > Yui > Ritsu

Tsumugi & Mio ones are definitely worth listening.
