The ",?" is due to the credit arrangement - I can't tell if Kitajima

Suemera was also music producer on Guilty Gear Judgment, and Ogawa
also performed guitar work there. That score isn't too bad, by the
way, although it's not that great compared to Ishiwatari's work.

Tracks 01, 02, and 04-08 are from Guilty Gear XX
(well, some originate earlier, but let's not split hairs)
Tracks 03 and 09 are, curiously enough, from Guilty Gear Isuka
Everything else is original, I'm pretty sure

Couldn't find any in-game use of the last two tracks..
And yes, there's only five themes for eleven stages.
