I was punching in some composer names into J-WID just to see if anything interesting popped up, and it seems that JASRAC has removed the specific composer info for this and the
Chronicle Heroes soundtrack. All the tracks now only show the generic "Capcom Sound Team" or "T's Music."
(
Battle Heroes info is still there.)
The track by Takatsugu Wakabayashi on this album is one of the ones now credited to T's Music, so it seems like he's part of their sound staff. Which'd of course explain how he ended up on this album in the first place.
