Anyway, if you have directory-based music organization, Navidrome won't take that, sadly. However, it will take m3u playlists.
So I can just ls playlistdir/* > Playlist.m3u and get that directory as a playlist. Simple, lazy solution.
Oh, you can also add internet radios to Navidrome.
And one cool trick, which is also pretty good to test out Navidrome without effort, in Termux it is already in the repos, so you can just effort-free apt install navidrome, run it and play around.
