A Spotify daemon in the spirit of MPD, Music Player Daemon.
Right now, spotifyd can search, add to a queue, play the queue (randomly or in order), add playlists, remove playlists, edit playlists. For my use it's pretty much feature complete but if you feel something is missing, please open an issue (or better yet, send a pull request with a patch for the new feature!).
Spotifyd is fairly scriptable and hence features can be added without modifying the source code of spotifyd itself. See the scripts directory for examples.
Building is done with a single command:
make
Installation is done with a simple make install. If you're running Arch Linux,
there's a package on AUR as well.
libspotify and alsa (as far as I know!).
For now spotifyd only accepts conenctions on a socket, or a pair of sockets,
specified in ~/.spotifyd.rc. The example config listens uses /tmp/spotifyd
as a unix socket and 127.0.0.1:12345 as an network socket. For
testing purposes, one can connect to spotifyd with socat:
socat UNIX:/tmp/spotifyd -
or with telnet:
telnet 127.0.0.1 12345
The following commands are implemented in spotifyd. The same list can be generated by sending the command "HELP" to the sever:
- SEARCH str - Searches spotify for str.
- CUR_PLAYING - Returns the currently playing song.
- QLIST - List content of the queue.
- SLIST - List search results.
- QRAND - Toggle queue randomness on/off.
- QADD n - Add song n from search results to queue.
- QCLEAR - Clear the queue.
- QPRINT - Toggle queue printing behaviour.
- QRM n - Remove track n from queue.
- PLAY n - Play song n in queue.
- PREV - Play previous song.
- NEXT - Play next song.
- PAUSE - Toggle play/pause.
- PL - List available playlists.
- PLCREATE s - Create new playlist with name s.
- PLDELETE n - Delete playlist n.
- QADDPL n - Put playlist n in queue.
- PLADD n p - Add track n from queue to playlist p.
- LINK s - Looks up spotify uri s and adds to queue.
- PLRM n p - Remove track n from playlist p.
- VOL p - Set volume to p percent, where p is in the range 0 to 100.
Start the server like this:
./spotifyd
or
./spotifyd --no-daemon
to run the server in the foreground.
I created a bash function so that I don't have to type the socat command all the time:
sc () {
echo $@ | socat - UNIX-CONNECT:/tmp/spotifyd 2>/dev/null
}
I the use it from the shell like this:
~/spotifyd $ sc search art blakey | head -n4 # search for art blakey, show the top 4 hits.
0 | Moanin' | Art Blakey & The Jazz Messengers
1 | Moanin' | Art Blakey
2 | Along Came Betty | Art Blakey
3 | Along Came Betty | Art Blakey
~/spotifyd $ sc qadd 0 # add search hit 0 to queue
Adding: Moanin' | Art Blakey & The Jazz Messengers
~/spotifyd $ sc play 0 # play song 0 on queue
Playing: Moanin' | Art Blakey & The Jazz Messengers
~/spotifyd $
The queue now contains one song, wich can be shown by:
~/spotifyd $ sc qlist
0 | Moanin' | Art Blakey & The Jazz Messengers
~/spotifyd $
If I want to add many songs, I just use my bash skills:
~/spotifyd $ sc search rolling stones | head
0 | Gimme Shelter | The Rolling Stones
1 | Paint It Black | The Rolling Stones
2 | (I Can't Get No) Satisfaction - (Original Single Mono Version) | The Rolling Stones
3 | Start Me Up - Remastered | The Rolling Stones
4 | Sympathy For The Devil | The Rolling Stones
5 | Angie - Remastered | The Rolling Stones
6 | Sympathy For The Devil | The Rolling Stones
7 | Rolling Stones T-Shirt - Radio Edit | Dada Life
8 | (I Can't Get No) Satisfaction - Mono Version | The Rolling Stones
9 | Brown Sugar - 2009 Re-Mastered Digital Version | The Rolling Stones
~/spotifyd $ for i in `seq 0 9`; do sc qadd $i; done
Adding: Gimme Shelter | The Rolling Stones
Adding: Paint It Black | The Rolling Stones
Adding: (I Can't Get No) Satisfaction - (Original Single Mono Version) | The Rolling Stones

~/spotifyd $
That didn't require so much skills. But lets say that I don't want those two duplicate songs?
~/spotifyd $ for i in $(sc search rolling stones | head | sort -t'|' -k2,2 | uniq -f1 -w10 | sort | cut -d'|' -f1); do sc qadd $i; done
Adding: Gimme Shelter | The Rolling Stones
Adding: Paint It Black | The Rolling Stones
Adding: Start Me Up - Remastered | The Rolling Stones
Adding: Sympathy For The Devil | The Rolling Stones
Adding: Angie - Remastered | The Rolling Stones
Adding: Rolling Stones T-Shirt - Radio Edit | Dada Life
Adding: (I Can't Get No) Satisfaction - Mono Version | The Rolling Stones

~/spotifyd $ sc qlist

~/spotifyd $
Okay, so no one would do that in practice. The point is just that the standard shell along with the unix tools are really powerful and allows you to do manage the queue efficiently.
Configuration is done by placing a config file called .spotifyd.rc in the $HOME dir of whoever
runs spotifyd. An example is provided. There are several configuration options available. The port
(or path if a unix socket is being used) specifies where spotifyd should listen. The bitrate option
tells spotifyd the preferred streaming bitrate. Acceptable values include 96, 160, and 320. A
username and password can optionally be provided so that spotifyd doesn't have to prompt for them
when it launches.
If you want spotifyd to start at boot you need to add some sort of init script.
In the init/ directory there are examples for some init systems.
Every application using libspotify requires an appkey. However, spotify don't allow you to share it openly in plain text, only compiled as a part of your program. As I want anyone to be able to build this program, I supply appkey.key, a binary version of the appkey. You can feel free to inspect this binary, or request your own appkey from spotify then download and overwrite the binary yourself, if you don't trust me.
Spotifyd requires Spotify Premium. This is a requirement on all applications using libspotify unfortunately.
Spotifyd uses libalsa to play audio. If you are running a distribution that uses pulseaudio, this means that you may not be able to play audio via ALSA and PulseAudio at the same time. To fix this, audio from alsa needs to be piped to pulseaudio.
For Arch Linux users, this can be done by simply installing the pulseaudio-alsa package.
The project is licensed under GPLv3 with the exception of the files audio.h,
audio.c and alsa-audio.c that are from the libspotify examples. The function
on_music_delivered in callbacks.c is also from the libspotify documentation.
Did spotifyd behave unexpectedly? File an issue and I'll look into it.
If spotifyd crashes with a nasty error message, I'd like you to provide a backtrace in the issue report. To create a backtrace, to the following:
- Edit
Makefile, append-gto theCFLAGSline. - Rebuild the program with
make clean && make. - Run spotifyd in GDB
gdb ./spotifyd- If GDB is not installed on your computer, install it through your package manager.
- In GDB, type
run - Do what you normally do to make the application crash.
- When it has crashed, type
btin the GDB shell.
Post the output of the bt command together with a description of how the crash
can be reproduced to the issue tracker.
Found a bug or want to add a new feature? Great! Send a pull request and I will take a look. Let's make this the greatest Spotify client out there!
