Have you tried reading any official documentation at all so far, in this “issue”?

Oversized music library + Navidrome with a few playlists that build as you go. There are apps for most clients i would guess.

ProtonVPN, Mullvad and NordVPN. Bypass traffic that doesnt need to exit trough the tunnel as needed.
