I’m trying to bring this up again.
Plex should incorporate full handling of .m3u playlists stored in Media folders (Music/Videos). This is fully possible and done by others (Emby) and we should get it too cause some of us (like me 
) happily paid for the product so it would be fair not to sleep on this request which is much much simpler than others on this forum.
Thanks
Salvatore
