Something something director's intent

Though, there have been a few times where the music choice was objectively bad, like the stretch in upper Kholusia where it plays that one 'get hyped' ShB remix of the Prelude theme for like 8 quests and about a level and a half when really the events only called for it when you were about to launch the Talos

That and the midboss theme they retroactively added in 5.2; it kinda ruins the effect of Insatiable when you hear a watered down version twice before you actually get to hear it. They shoulda just saved it for post 5.0 dungeons like HW did with Revenge Twofold, but that was endboss only.

At least EW's midboss theme doesn't grate the same way.

Yeah, personal music for your own repeatable stuff seems reasonable. A FFXIV back in 2013 had the foresight to give players some say in mount music, don't see why the one in 2023 can't respect its players the same.
