I downloaded a bunch of songs from the game yesterday. I like most of the songs from the Gingaza girls, but my favorites are from Eden. This Daikoku girl sounds like a total dork, but I really like her songs. Surprisingly my favorite is 純粋と奔放 from Nikako and Hatsumi. Nikako didn't stand out to me at all when I read her bio all the way back when the anime aired.
