Spotify
Spotify is a commercial music streaming service.
Installation
To install the standard Spotify desktop application, add to system packages:
environment.systemPackages = with pkgs; [ spotify ];
Local discovery
To sync local tracks from your filesystem with mobile devices in the same network, you need to open port 57621 by adding the following line to your configuration.nix:
networking.firewall.allowedTCPPorts = [ 57621 ];
In order to enable discovery of Google Cast devices (and possibly other Spotify Connect devices) in the same network by the Spotify app, you need to open UDP port 5353 by adding the following line to your configuration.nix:
networking.firewall.allowedUDPPorts = [ 5353 ];
Spotifyd
The alternative client spotifyd is available as a package, nixos module, and home-manager module.
spotifyd can either act as a spotify-connect device and the local LAN without the need to authenticate.[1] It can also run through a manual login using oauth[2] If installing spotifyd as a package or as a systemd service via home-manager, give it oauth credentials using:
spotifyd auth
The authentication codes are stored in the cache directory for spotifyd.
spotifyd connects to spotify as a spotify-connect device. It offers no controls of its own, but can be controlled via playerctl or spotatui.
Troubleshooting
If you get: libcurl-gnutls.so.4: no version information, clear your Spotify cache: rm -rf ~/.cache/spotify
