Not really a fan of this particular song, but stretched out 4:1 it sounds kind of mellow and what artifacts I hear just make it a little bit trippy, while making any Richard-Clayderman-esque parallel-6th abuse and other easy-listening cliches in this arrangement less noticeable. So, that's an improvement.
