Of all Zeldas, I have to say Majora's Mask. I love the overall melancholy tone of a lot of its tracks. Its frantic march version of the Legend Of Zelda theme that plays one the field is fun. I love the music of Clock Town too, starting off all happy and upbeat, almost as if its in denial of what is about to happen, but as the days pass the theme takes on a darker tone, like it is realizing its inevitable fate. The dungeon themes were great as well, perfectly setting the tone for each. The boss themes for the game are unforgettable, the theme for the mini bosses and main bosses are hands down my favorites in the series, and the final boss themes are just amazing. And the main theme of the game; absolutely haunting!
