Tailscale

 services.tailscale = {
    enable = true;
    openFirewall = true;
    authKeyFile = path-to-key;
    extraUpFlags = [
      "--login-server=https://your-instance" # if you use a non-default tailscale coordinator
      "--accept-dns=false" # if its' a server you prolly dont need magicdns
    ];
  };

Tidal-dl-ng Shell

nix-shell tidal.nix (or whatever you call this file)

{ pkgs ? import <nixpkgs> {} }:

let
  pythonEnv = pkgs.python3.withPackages (ps: with ps; [
    pip
  ]);
in
pkgs.mkShell {
  name = "tidal-dl-ng-shell";

  buildInputs = [
    pythonEnv
    pkgs.ffmpeg
  ];

  shellHook = ''
    python -m venv .venv
    source .venv/bin/activate
    echo "🎵 Tidal-dl-ng environment ready."
    pip install python-ffmpeg
    pip install tidal-dl-ng
    echo "Ready to rock. Available command: tidal-dl-ng"
  '';
}
