I completely understand where you’re coming from because I was also annoyed at what I assumed was laziness on Nintendo’s part. I’m not even gonna argue with you about it because I also didn’t realize how low key dope the music was until I saw some music majors talk about it on another site.
So basically, unlike the other Zeldas, BOTW has music from a lot of the other Zelda games even from Zelda 1 and I’m not talking about the main theme you hear from riding the horse. They took these themes and remixed them into songs in certain areas of the game. If you’re not exploring enough you’re not gonna hear it. So for example, Death Mountain’s theme came from Dungeon 9 in Zelda 1. The village with the birds has the same theme from Dragon Roost island in Windwaker mixed in the track. There’s other songs they have playing BACKWARDS and STILL sound good, that’s cot damn genius. But the reason you don’t notice it is because the main theme of BOTW is melancholy and desolation. All Link’s friends are dead. He can’t remember shyt. There’s ruins everywhere because Calamity Ganon and the corrupted Guardians destroyed and murdered most of Hyrule.
Anyway my favorite tracks are the battle music, divine beasts in particular, boss musics, hyrule castle, rito village, the village by the sea with all the black people cause im also Carribean and theres another song i don’t know the name of it spent like 30 min looking for that shyt i give up, the trailer music, main theme and last and not least, my fav from the DLC, Maz Koshia
