Actually, I'm gonna add another really simple option: Lyrion (Formerly Logitech Media Server). My wife swears by this one, supports local library, integrates with LastFM, and if you use Tidal, Qobuz, Deezer, or Spotify, you can integrate your streaming service with your local library for radio mixes.

Can install it right on a laptop or PC and connect to wherever your music is (local on the machine, on a NAS, etc.). After you install it, you can access it directly via a web browser or webapp, which will make it accessible from desktop or phone.

There are two main ways you can do it. You’ve already mentioned you have your library/music files, so that’s a good start, you’re basically looking for a way to access it on other devices. The first way would be to set up an old PC/rent a cloud server, and set up the service you want to use, though for now this may be a bit too complex if all you want to do is stream your own music, and have no experience. That being said, it’s always good to have a look and see, there may be a tutorial that works for you if you want to go down this route.

You’ve mentioned Navidrome, and it’s a good shout, basically just looks at the folders of music you have, and lets you stream them to your phone/PC (and more) like Spotify or Google Music. For the simplest possible setup, I’d recommend a service like Pikapods (https://pikapods.com), which essentially selfhosts applications for you, and gives you access to the files. For Navidrome, for 50GB storage (and the recommended settings of 1 CPU core and 0.5GB RAM), it’s $3.01 a month, which, though not free, is very affordable if that’s all you want to do, plus they handle updates, etc. You shouldn’t need to set any variables, and can upload your music to their service via FTP (File Transfer Protocol, a way to copy files to another PC/server from your PC), and they have docs on how to do that on the site.

Hope this helps :P

What's wrong with just throwing MP3s on an SD card, or hard drive?

Edit: Love how I have 4 upvotes, 4 downvotes. So a pretty divicive statement I've made. Yet nobody has told me why mp3s on local storage is or is not a solution for self hosting music. No opinions shared, other than angry arrows in both directions.

Cool. Cool. Cool. Cool.

Navidrome server. Use podman. Buy a Fully qualified Internet address first, then go to cloudflare and proxy your IP to the new. Address. Finally in android install Ultrasonic or Subsonic and go to your server.

You don't need to have a Fully qualified Internet address. But I like it better than having to remember 55.655.67.533. but the IP address still works fine. The thing about the cloudflare proxy is that it never reveals your IP. So in case someone might be snooping around, they gotta get past cloudflare first.

Yunohost and Navidrome.

I popped some songs onto my Jellyfin server, and that's worked out.

I was even able to stream it to my car using Android Auto.

What do you want it to do? If you have all your music, a bunch of folders with MP3s works.

I just use Auxio on Android or GNOME Music on Linux to listen to my downloaded files, and sync them via Syncthing.

@zeromoney I have a self hosted streaming service for music with #Jellyfin. But i think there's no an easy way to deploy it. You need to have some basic linux knowledge.

@selfhosted

You pretty much just need an Intern et connection though it would be best if it was unmetered. It doesn't take much as far as resources go to host music. You could also think about just syncing playlists to your mobile device. Lots of people forget about that.
