As an excercise to better understand the music tool I made a "cover" of the song "Surviving" by Namnambulu. I say "cover" with quotation marks because I suppose it's more... uuuh... "inspired by" =)

[sfx]

Edit: The sound quality in the web player in Chrome is really bad for me. Either try another browser, or click that little "sfx" link under the player to copy the song into pico8 itself.
