In Majora’s Mask, one of the first songs you learn is the “Song of Healing.”  The guy who teaches it to you is the Happy Mask Salesman.  Probably one of the most terrifying characters in the game.  In the end, I guess it’s fitting, because the Happy Mask Salesman teaches you a very eerie sounding song that is the “Song of Healing.”  Not even putting a backing beat on the song can make it sound less eerie.
