Running Grapheneos right? Running Grapheneos right?

If you go with a subsonic server like navidrome, you could pair that with something like Symfonium (paid, and only available on google play unfortunately). That’s what I do currently, until something better comes along (Tempus is starting to look nice!)

I do this as well lol, although on my phone I go one whimsical step further and offline cache the music from my navidrome server.
