Any "Music Server" apps that will let me stream music to my phone, and sync an offline copy?

Long story short, I've had things like Google music, Spotify, Deezer etc, but I'd like to avoid paying monthly all the time to get decent offline sync for music.

Ideally I'd like something that would either turn an RPI device into a music server or run as a package on my NAS, with a mobile app that lets me stream the music and sync it offline to the phone for when I'm out and about without any signal.

Anything about that may achieve this?

Answered my own question here somewhat I think - Subsonic looks like it would do the trick, but it's all gone a bit crazy there recently with the developer going from open source to closed source.

I think plex does something like this.

I think plex does something like this.

Yes plex can do similar but you need plex pass for offline sync and it's too expensive for me to consider it.

I can recommend Subsonic for this.
I've been using on my little Microserver for years, without any trouble. Converts FLAC to MP3 with no trouble, and handles podcasts very well.

Why not just upload to Google Music? You don't need to pay the subscription.

Yeah you can upload i think 50,000 tracks to google music with nothing to pay
