There is a specific track that plays during certain instances in Kingdom Hearts Birth By Sleep. It is not the 'regular' boss theme (Unforgettable); it is also not specific to any world, because I have at least two examples of where this music plays:
- As Aqua, shortly after you meet Prince Phillip, where you are first tasked with taking out Maleficent's goons;
- As Aqua, when you fight alongside Mickey against Unversed in Radiant Garden (example)
I can't find an example right now, but I'm pretty sure it isn't specific to Aqua either. Can anyone tell me which track this is?
