It seems like I would have heard this song before. I guess I'm just so used to Zelda music, it's hard to tell. I wish I had played Ocarina of Time as a kid! It was even the highest rated video game ever! I really did appreciate how well paced it was. It worked well for its length.
I was a little disappointed at first that this wasn't that long. I now like it much more. It really does change in tone. It starts off as a soft adventure, but then it gets even softer. Even with the same rate, I noticed the change.
