"Vs. Bellum" - Plays during the fight against Bellum in the Temple of the Ocean King
"Bellum and the Ghost Ship" - Plays when you fight the Ghost Ship after Bellum possesses it
"The Final Boss" - Plays when you fight Bellumbeck
Truly a tragedy to find the climactic songs are missing and don't seem to be requested, and I can't find the Bellumbeck theme ANYWHERE.
