I LOVE all of the Ocarina warp songs. My favorite though, would have to be the Bolero of Fire. It has a sense of urgency but it's also very melodic. I really wish it would have been made into a full song though, instead of just a ten second tune. Actually, I wishh all of them were full-fledged songs.
The Serenade of Water is a close second though, because it's so soothing and beautiful.
