OK so, anyone wanna point me to any time where there's any kind of bombastic music played in the hours of gameplay that we've gotten so far? The music in the latest trailer is likely just promo/trailer music like we've heard for Twilight Princess before (one of the tracks was reused for the first Skyward Sword trailer).
Off the top of the dome, the Steppe Talus fight and entering fully active and mobile Guardian encounters showcase themes with more bombast beyond the combat music for smaller grunt enemies, but even then we're only seeing music associated with the plateau and the area of hyrule field just north of it.
people should be ready for the fact that each distinct area and exploration therein will be defined by far more muted and subtle accompaniment meant to underscore a more desolate and ruined landscape
when larger scale more involved themes come in (they def will) they will have FAR more impact. the same can be said for whenever voice work comes in, and also sort of when you encounter NPCs. it should feel like a bit of an oasis.
those are my hopeful thoughts, at least
