I've been roaming on the forum and seen the post of Eloah on the music in game, especially in Ultima Thulé where we don't have a second music.

Then Asako said that :

And why not adding more to that than just a simple "Orchestrion" ?

How about this :

You can select music for Town, Outside map, Outside battle, dungeon battle, Rank A battle, Rank S Battle, mount,

For Town and Outside map you could select 2 music, one will be played in the day, the other one at night.

Those parameters can be changed and saved with at least 5 slot of presets you can make (According to your mood).

If anyone got more idea about this, how about adding it to this thread ?
