Personally, I am not a fan of The Legend Of Zelda series and did not played OoT, but this OtoMAD is great! Especially if you want to relieve some Nintendo 64 memories by just familiarizing with the MADs you are seeing in this post.
Also, auto loop at end of song.
Note for safe watchers: SAFE TO WATCH.
Song: Heaven And Hell by Mutsuhiko Izumi / Sources: The Legend of Zelda: Ocarina of Time / Interim: Hammer Melody
(My misc. opinion on certain point: Soothing interruption by game ocarina melody at 1:11)
