Gerudo Valley has been a favorite of mine for a long time. Koji Kondo is a genius. The NES Kid Icarus medley, the all-NES medley, the Kirby Boss Theme medley, and the WarioWare, Inc. theme are a few of my favorites. The King K. Rool/Gangplank Galleon music is great, too. I downloaded the entire soundtrack a few days ago. It's amazing.
