[Phonograph]

actually, I think you can assume the bgm are from the anime and made by sakimoto
since it's a "sword of uruk" album, the ost related to that series is only made by sakimoto
(there are two series: aegis and sword -even if they don't follow themselves, it's still the same series)

and that ozawa's bonus track, I don't think that thing is heard in the anime but rather in some random game (maybe medley of some nightmare of druaga tracks)
