Well, like they said, it doesn't change, for one thing. Second, I see what you're getting at, but this simply isn't Zelda music. This is more fit for Lord of the Rings or Final Fantasy. Zelda has very unique and interesting music, and it fits perfectly with what the game is like. That part of Zelda, the part that seperates it from other games that may initially look like it, is very obvious. I'm doing the Nintendo Gallery, and I've filled up the entire Monster room with all of the enemy statues. Never before have I seen a more colorful cast of enemies in a game, and they are also very unique; no generic enemies at all, like Chimeras or Werewolves. The music reflects that.
But that was cool music.
