How do you play Electric Duet music files outside of the original disk?

[Brian <bpicchi@gmail.com>]

I'd like to add some music to a new game I'm working on (don't worry,
not during the actual game play, that is far beyond me), but perhaps
in the background during the intro screen.

I have all the music files and the actual music player extracted, now
what code do I use to play it in BASIC?

Thanks.
