How share playlists with non Apple Music friends?

Hey, so, my friends and relatives use Spotify, Pandora, Amazon, and Apple Music.

I'd love to be able to share my playlist (remember, it is just a list, not the music!) with them. Of course, sharing Apple Music playlists to Apple Music friends is no problem.

But how do Apple Music users share their playlists to these other popular services? Not being able to do so has really taken away one of the great joys of music among friends.
