I've always been a fan of Jack Fliegler's covers, my absolute favourites being Mad Jack and Final Bowser.
This remix from Banjo-Kazooie has been close to my heart since high school. It's so high energy and also romantic.
And I gotta give a shout-out to this one track in Majora's Mask. I find it funny that such a strong piece of music was only used for one room for one small side quest. You could potentially finish the game without ever hearing it.
Now that I've completed Faith 3 as a game, time to more fully appreciate the soundtrack, especially how they turned Atari age sounds of my youth into something unnerving.
