Option to remove battle theme in dungeons?

[Ninix]

Problem is (and I'm pretty sure you're referring to stuff like the music that plays when entering Pharos Sirius) is that the specific dungeon themes are only like 90 seconds long and do not loop well. They have a very definite 'beginning' and 'end' to the music and if they just disabled the existing battle music and looped the dungeon themes it'd get annoying really quickly. So unless they go and rearrange/rerecord those pieces to make them longer, they can't really do this for the current dungeon themes.

Hopefully for future dungeons they'll do what they did with Coil and the hard-mode 4-mans where they have two arrangements of the same looping dungeon theme, a normal one and a more aggressive battle one, and the game seamlessly swaps between them when you enter/exit combat. It's a pretty cool effect.
