Funny thing, I did the same thing (used Jellyfin for several years, then Navidrome for probably a year) and now moved back to Spotify. I think the discovery of music in self-hosted apps is worse. I like to listen albums mostly but I always happened to listen to the same handful of albums, only because those were the first on my mind. I think Navidrome's smart playlists have potential though. Did you come up with a good way to rotate the music?
