My favorite soundtrack is a huge win in Zelda: OoT because of this one song that I am in love with; the mission related to it, the place where it happens, what it does, and it:

I love it! You can also play it on your Ocarina.
Of course, in OoT there's also the wonderful Nocturne of Shadows, and The Forest Dungeon's song. My favorite non-playable song is Gerudo Valley. That one is
so fun and just, awesome. It is perfect for the setting as well.

For some reason there is a ton of blank end, so just saying you can stop it at 1:32. Also, the song fits the puzzle solving but sneaking level area.
I also went to the New York Zelda Symphony. Gerudo Valley was an encore, and I LOVED it! That was awesome.
So, yeah, OoT wins the music contest!
