Favorite original music: Bowser Battle Themes, Good Egg Galaxy, Gusty Garden Galaxy, Star Festival, Speedy Comet, Purple Comet
Favorite remixed music: Toy Time Galaxy, Bowser's Road, Sweet Sweet Galaxy, "Athletic Cosmos"
Speedy Comet is my top-favorite theme in the whole game. The tension and the suspense of either racing against the clock or trying to avoid all danger is nailed perfectly.
