My favorite music.

I really like the music in Ronfaure. Something about it.. I don't know xD

I also really like the Sanctuary of Zi'Tah theme.

Gustaberg, Sanctuary of Zi'Tah , battle music when in a group at Bibiki Bay, and the begining of Alexander Battle.

Theme to Divine Might (Only used for that BC I think, shame). Still probably the most epic instanced battle in the game. (When it was capped and somewhat difficult obviously).

Shinryu BC theme is also pretty good.
