As somebody who has sunk over a decade into iTunes it really is shit that most people just post Spotify playlists.
MusicThread is a bit basic but does the job kind of https://musicthread.app/
would it be totally irresponsible to make a dedicated .rss feed for the playlist, and then just directly link to a smattering of .mp3s, and then listen to it all in a podcasting app? 
If you find a responsible way for me to share music without the obvious putting me in trouble, absofuckinglutely let me know, it tears me apart to have this giant library and few people to share it with
