I have a special softness in my heart for recordings and covers of Super Mario Brothers music. Found this one via Boing Boing and going to give it a listen. 🙂

The complete soundtrack to Super Mario World, covered by one man using dozens of instruments. Roughly in game order, faithful to the originals, with some bizarre artistic license thrown around. A private hobby made public. Dedicated to Koji Kondo. –XOC
