This is the OST for Dynamite Headdy. Truly an experience.

From the Mario 64 beta build on July 29th, 1995.  This track only plays in an encounter with the Wario Apparition. Every copy is personalized

Track 3 is actually dated a few weeks before Spaceworld, it's a variant of the Metal Mario theme made after the Starman powerup was canned.
