OOCO-26: Shining the Holy Ark Original Soundtrack

[Hellacia]

This CD features none of the game's original music? The title says original soundtrack, but it's classified as an arrangement here. The titles usually aren't that misleading when they actually say original soundtrack, but there have probably been a couple of instances where this has happened, so I'm just wondering.

EDIT: The Shining Force III soundtrack, which was also composed by Motoi Sakuraba, seems to be classified the same way. Maybe this is just a trend with the releases of his earlier music?
