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.

Tidal has been pretty good for me over the past 5 years. I don’t know what your criteria are, but for me it’s something like 1) is the catalog big enough to offer 90% of what I’m looking for and 2) no advertising if I’m paying for the service. It ticks those boxes. I imagine it’s only a matter of time until they introduce the bullshit tier where you’re paying and being advertised to, but for now you get what you pay for.

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

Val!

To add to this, there’s even the capacity to add usb dacs if the underlying distribution supports it. Picoreplayer was my introduction to these tools and I’m pretty sure it’s my final destination. Can’t recommend it enough if they have the time and curiosity to get it set up.

I would also add that if the person OP is asking on behalf of is not so inclined to get into the technical parts and okay with possibly throwing money at the project, volumio is there. I tried this first and appreciated it for what it was, but I wanted features behind the pay wall which are readily available for free with pCP.

I ran into this exactly, but it turned out to be device compatibility. I could never find it in the play store on the (x86) Chromebook, while it always showed up as you’d expect on the arm android.

Backblaze B2, which I’m pretty sure is a repackaged S3 provider, or you can just skip them and go directly to AWS S3; though, both aren’t drag and drop user friendly like onedrive or gdrive. But both work well if you invest a little time with something like rclone.
