I like most of the music (just not the very few pop-esque ones... like Yuna's Sub Theme, or the Airship ones) as the genres are very diverse orchestral styled ones, I like the music that plays when you are in the Via-Infinito most.

FINAL FANTASY XI
not the city themes... NOT THE CITY THEMES!!!! ... probably the battle themes :]
