Spotifyd

An open source Spotify client running as a UNIX daemon. Spotifyd streams music just like the official client, but is more lightweight and supports more platforms. Spotifyd also supports the Spotify Connect protocol which makes it show up as a device that can be controlled from the official clients.

Spotifyd requires a Spotify Premium account.

What happened to the old spotifyd, written in C?

Unfortunately, Spotify decided to kill the libspotify library we used, and hence we had no choice but to rewrite everything.

Installing

Travis CI builds binaries for systems running Linux on AMD64 and ARMv6 which should run on any Raspberry Pi model. The binaries can be found here. Other systems have to build from source for now. You will need the ALSA package for your distribution, e.g. libasound2-dev on Ubuntu.

Detailed install instructions can be found on the wiki.

Build from source

The Rust compiler and Cargo package manager are needed:

cargo build --release

The resulting binary will be placed in target/release/spotifyd.

Alternatively, the package can be installed into the user's home directory by running the following command:

cargo install --path .

This method also allows further configuration by specifing more feature flags as shown further down.

The default is to build spotifyd with an ALSA backend, but it is possible to build with other audio backends, making Spotifyd available on platforms other than Linux, by adding the --no-default-features argument to cargo and supplying an alternative backend (see the Configuration section).

Configuration

Spotifyd will search for a file name spotifyd.conf in the XDG config directories (meaning, a user's local config is placed in ~/.config/spotifyd/spotifyd.conf, a system-wide config in /etc/spotifyd.conf or /etc/xdg/spotifyd/spotifyd.conf) and has the following format:

# ~/.config/spotifyd/spotifyd.conf
[global]
username = USER
password = PASS
# password_cmd = command_that_writes_password_to_stdout  # can be used as alternative to `password`
# use_keyring = true                                     # can be used as alternative to `password`
backend = alsa                                           # run `spotifyd --backends` for possible values
device = alsa_audio_device                               # run `aplay -L` for possible values
# control = alsa_audio_device                            # device for the mixer, if not the same as 'device'
mixer = PCM
volume_controller = alsa                                    # or alsa_linear, or softvol
# on_song_change_hook = command_to_run_on_playback_events
device_name = device_name_in_spotify_connect             # must not contain spaces
bitrate = 160                                            # or 96, or 320
cache_path = cache_directory
no_audio_cache = true                                    # use credentials-only caching
volume_normalisation = true
normalisation_pregain = -10
zeroconf_port = port_number                              # the port used to start the Spotify discovery service 

Every field is optional; Spotifyd can even run without a configuration file. Options can also be placed in a [spotifyd] section which takes priority over the [global] section. This is useful when you run applications related to Spotifyd which shares some, but not all, options with Spotifyd.

Values can be surrounded by double quotes (") which is useful if the value contains the comment character (#).

Cache path

The line cache_path = /cache_directory defines the cache path, where Spotify's cache-files are stored. These cache-files are used to avoid re-downloading data when a track is replayed. Here the cache path is set to store the cache-files in /cache_directory. To save space on the system disc you can use another directory, for example /mount/disk/spotifyCache. Spotifyd does not create a missing cache path, so the path must exist. The cache path is not expanded by the shell: paths containing e.g. ~/ or $HOME/ will not work.

Alternatives to storing your password in the config file

• password_cmd config entry

  This feature allows you to, in the config file, provide a command that prints your password to stdout, which saves you from having to store your password in the config file directly. To use it, set the password_cmd config entry to the command you would like to use and remove the password config entry, which, if present, would take priority.

  For example (using the password-management utility pass) ...

  # ~/.config/spotifyd/spotifyd.conf
  password_cmd = pass spotify

• use_keyring config entry / --use-keyring CLI flag

  This features leverages Linux's DBus Secret Service API (info) in order to forgo the need to store your password directly in the config file. To use it, complile with the dbus_keyring feature and set the use-keyring config entry to true or pass the --use-keyring CLI flag during start to the daemon. Remove the password and/or password_cmd config entries, which, if present, would take priority.

  Your keyring entry needs to have the following attributes set:

  application: rust-keyring
  service: spotifyd
  username: <your-spotify-username>
  

  To add such an entry into your keyring, you can use secret-tool, a CLI used to communicate with agents that support the Secret Service API:

  secret-tool store --label='name you choose' application rust-keyring service spotifyd username <your-username>

Shell used to run commands indicated by password_cmd or onevent

If either of these options is given, the shell spotifyd will use to run their commands is the shell indicated by the SHELL environment variable, if set. If the SHELL environment variable is not set, spotifyd will use the user's default shell, which, on linux and the BSDs, is the shell listed in /etc/passwd, and, on macOS, is the shell listed in the output of dscl . -read /Users/<username> UserShell.

Command Line Arguments

spotifyd --help gives an up-to-date list of available arguments. The command line arguments allows for specifying a PID file, setting a verbose mode, run in no-daemon mode, among other things.

Audio Backend

By default, the audio backend is ALSA, as ALSA is available by default on a lot of machines and requires no extra dependencies. There is also support for pulseaudio and portaudio.

PulseAudio

To use PulseAudio, compile with the --features flag to enable it:

cargo build --release --features="pulseaudio_backend"

You will need the development package for PulseAudio, as well as build-essential or the equivalent in your distribution.

PortAudio

To use PortAudio (works on OSX), compile with the --features flag to enable it:

cargo build --release --no-default-features --features="portaudio_backend"

You will need the development package for PortAudio (brew install portaudio), as well as build-essential or the equivalent in your distribution.

Usage

Spotifyd communicates over the Spotify Connect protocol, meaning that it can be controlled from the official Spotify client on Android/iOS/Desktop.

For a more lightweight and scriptable alternative, there is the Spotify Connect API.

D-Bus MPRIS

Spotifyd implements D-Bus MPRIS which means it can be controlled by some generic media playback controllers such as playerctl as well as some tools specifically designed for use with the official Spotify client such as sp (requires changing the DBus service name to spotifyd instead of spotify).

The D-Bus server is currently experimental. Enable the dbus_mpris feature when compiling to try it out.

Running as a systemd service

A systemd.service unit file is provided to help run spotifyd as a service on systemd-based systems. The file contrib/spotifyd.service should be copied to either:

/etc/systemd/user/
~/.config/systemd/user/

Packagers of systemd-based distributions are encouraged to include the file in the former location. End-user should prefer the latter.

It should be noted that some targets are not available when running under the user directory, such as network-online.target.

Control of the daemon is then done via systemd. The following example commands will run the service once and enable the service to always run on login in the future respectively:

systemctl --user start spotifyd.service
systemctl --user enable spotifyd.service

Logging

In --no-daemon mode, the log is written to standard output, otherwise it is written to syslog, and where it's written can be configured in your system logger.

The verbose mode adds more information; please enable this mode when submitting a bug report.

Common Issues

• Spotifyd will not work without Spotify Premium
• The device name cannot contain spaces
