I haven't played through DT so my opinion might change but rn I really like the BGM. It's already a subversion of expectations and it creates the realization that you're not just going to some random tribal island. These are people with their own culture, interests and aspects. If it was pan flutes or something it would give an image that it's a smaller village or something less technologically advanced. But you can tell it's high traffic with a lot of passion flowing through it.
