Pepe, it's "Shinkyoku". Kinda like how the IIDX 14 song "Kigonshu" is often misused as "Oni genshu."
Anyway,
SANAGI - I still prefer the GFDM version overall. A little boring than the GFDM version, I must say.
emotion: uhhh
HOTARU - One of the best songs in the album yet
emotion: happy
Shiawase wo utau uta - Worst song in the album I guess. It's even more boring than the original. It TOTALLY lacks the good 210 BPM part.
emotion: slightly happy
Konoko no nanatsu no oiwaini - 3rd best in the album. Sounds as good as the original, although I still prefer the original, as it has the better sounding chorus
emotion: mixed, despite the fact that the song's about a newborn child
Yogo no ne - A good ballad song to listen to when in a bad mood.

emotion: sad
Gekkou chou - same as above, but less sad, plus it's a rock ballad song...
emotion: less sad than Yogo no ne
Akai suzu - nothing much to compare to the GFDM version, apart from having more violins
emotion: VICTOLY
SHIZUKU - pop'n version is still better. I still like how it sounds though.
emotion: as sad as Yogo no ne
Shinkyoku - The violins somewhat bore me, so I had it start in my iPod about 1:32 and end at 8:37.
emotion: The song is just plain weird, I don't know how I even felt after listening to this song
Sorasumi no hiyo to - NUMBUH ONE!
emotion: it's so nice to cry with the tune of the song, though usually, I don't feel like crying.
