My favorite Ocarina song is the Prelude of Light, just because of how peaceful it sounds, and because it is probably the most useful teleportation song (any time you need to become a kid/adult, just play this song).
Which song do I like the most? Well, before I tell you that, I just want to say one thing. I hate all of the adult warping songs, mainly because of the titles; the Minuet of Forest is not a minuet, the Bolero of Fire is not a bolero, the Prelude of Light is not a prelude, ect. Maybe I'm uptight... Any way, my favorite song is the Song of Storms.
