The official soundtracks to Ocarina of Time and Majora's Mask. Both albums include all the songs played in the games, along with the ocarina tunes. The music is in it's original form, meaning midi-quality tunes, not orchestral. I'm never bothered by the midi format; it just makes me feel like I'm really reliving the game. A complete tracklisting for OoT can be found here; MM here.
This album contains synthesized tracks from OoT, all remixed. The music is a step up from midi, but still sounds electronic. I think it's a fun album and is something a bit different to listen to. A nice edition to this album is the vocal version of "Epona's Song" sung by Emiko Shiratori (the artist who sang "Melodies of Life" for FFIX). This CD can be bought through GameMusic.com for $29.99.
