The Wing Commander Prophecy soundtrack is strange enough: it's two tracks from the game and a dozen randomly licensed techno/industrial songs. But now look at this: the Wing Commander Prophecy OST--from 1997!--on a cassette tape.
It's a real thing: for whatever reason, cassettes apparently had a longer shelf life in Thailand... and in 1998 a company called Rock Records licensed and released the Wing Commander Prophecy OST there.
What does it sound like? I have no idea, not having owned a cassette player since 1993.
