help finding the right pso2 ost

[Meta77]

Can anyone help me find which ost vol has profound darkness themes on it I've looked through all 6 vol listings but I do not see it?

One comment mentions the profound darkness in the OST vol4 but you wouldn't know from the listings.
The flower music should be Ooze which was from Phantasy Star IV and also IDOLA the strange fruit which was from PSO ep3 Card Revolution so... no idea where they would put it back.

Edit: judging from the samples on amazon jp part of the fight is there (cocytos, Idola joker, abyss and unfathomable darkness) but Idola the strange fruits isn't there as far as I can see.

Vol. 4, Disk 4:
9. Abyss (the teleporter music)
10. Unfathomable Darkness (Ooze, IDOLA the Strange Fruit, and The Whole New World).

Thank! So that would have all the phases? Wish transitions were more "spot on"

Tnaks Kondibon. There's only so much one can do without the actual thing.
