We have added the .wav file.

This is the audio file for those who wish to copy it onto a cassette tape.
While we still have a limited number of sealed tapes available on our website using original 80s-style cellophane, we are now providing the .wav file for those who prefer to copy it onto their own cassette tapes.
The tape is available in limited quantities on our website, so once they are gone, they’re gone.
