Don't have much time on analysing each song, so I'll just comment on highlights:
Genki+ is the perfect, more than perfect opening for a meccha anime. Or even a sentai. The first mental image I had was that Robots Festival

Shamuni Paradise is so
Chu! Natsu Party, so idol type. Even Miki adapted her voice to that song

. Could have been a debut song for Hinoi Team @____@
Unfortunately (?), Haru Beautiful Everyday didn't come in the .zip I downloaded, I can't comment about it. But overall, it's a good album, it gets 3 stars (out of 5 lol) from me. The pinku song didn't kill it, unlike Rainbow 7. Props to everyone, Morning Musume is giving me again the image of a group.
