I want to state upfront I am not a Dawntrail hater. I really love it (it seems to be a minority opinion). However, one thing I've been annoyed about with Dawntrail more than Endwalker is the lack of unique music in cutscenes.
Heavensward, Stormblood, Shadowbringers (and to some extent Endwalker) all brought their own unique themes that were utilized in scenes etc. They brought a "flavor," so to speak.
Dawntrail seems to recycle all the old themes, borrowing A LOT from Shadowbringers, which I feel music fits the themes and style of that expansion and feels really, really out of place in Dawntrail.
I feel music is so important to set the tone and give each story its own sense of identity. Dawntrail is so distinct with its visual style and flair and cultures, yet most of that is lost when we're slammed over the head with the Shadowbringers music cues.
Sorry, small rant.
