There have been a few mentions of Navidrome. I find it works well for sharing at an album or even artist level. It can do playlists as well. But you must explicitly choose what to share, at which point it’s generates a unique URL and will generate a web player and zip if you enable the option to download.

You can, of course, just make user accounts and distribute credentials.

If you’re needing to offer browsable folders to easily copy, basically a filesystem-like experience, it’s probably not the best tool.

Edit: one more thing to point out is that navidrome, jellyfin, and airsonic all construct music libraries differently. Navidrome is using tags, jellyfin uses file names, airsonic uses directory structure. Not sure about Plex.

I’ve had a good experience so far with two minipcs, mele quieter 4c for kodi, and a morefine m9 (I think this one is branded as mipowcat in the EU). They’re both n100, the m9 can go up to 32gb of ram although it is picky about what modules it will accept. I use the m9 for jellyfin and about 10 other services. Quick sync works great as far as I’ve tested it. For jellyfin I’m relying mostly on direct streaming, but I tried a few episodes with forcing some transcoding by using Firefox for playback and it worked fine.

I don’t think it’s actually still popular, but I’m just talking out of my ass here. I remember it made some waves a few months ago about finally having a new release after so long, and my feeling was a shitload of nostalgia brought it back into the internet spotlight, regardless of how many people are actually using it.

I gave it a spin again, purely for nostalgia. I could find no compelling reason to use it over my actual preferred player, foobar
