I love having full control over my music files, but one of the major pain points is moving between applications. Say I start using plex, get real comfy with my playlists, then one day I decide to try out Jellyfin. Sure, I still have all my music on there, but none of my playlists.
Is there some sorta solution I'm not aware of that allows for migration of playlists across platforms / applications?
"Anything" is a bit of an exaggeration. However, I wanted to mention m3u playlists as well, since it's one of the few (the only?) open, file-based solutions.
