I don't think it is a mess per say considering you're probably in an open environment where you're hopping around a lot more, rather than say in Ocarina of Time, where the battle music might be taking place in a dark dungeon more often
that said, like others have mentioned, it is believed the battle music may change depending on what region you're
I will say though that anyone expecting Breath of the Wild to have music and soundtrack on the level of Ocarina of Time are being unrealistic, that game in my opinion has the greatest soundtrack music of any game ever (even outside of Zelda)
