From out of nowhere, a guy by the name of XOC (Jason Cox) has released a collection of Super Mario World covers.

XOC sums it up quite well himself: “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”

Catchy and eccentric, the songs cover all the major themes from the
original Super Mario World on SNES, varying in styles from polka(?)
to.. well you’ll just have to listen. The songs are all available in
MP3 and OGG.

In other words, CHECK IT OUT, YO!
