I was surprised when I discover this tune was actually an .it file rather than a digital format, because I'd encountered it years before finding it in my mod file archives in the PC game Uplink.
What's curious is there's two versions of this - the modified one as heard here and as in Uplink, and what I presume is an original version which has a backbeat in certain places and is somewhat more up-tempo. I think I prefer this version though, it's one of the most chill pieces of music I have in my archives.
