Python based sound-cloud music server talking the MPD protocol.

NOTE: only basic MPD server daemon available yet

Main features currently supported:

  • Browse predefined set of favorite users (see "~/.pyscmpd/pyscmpd.conf")
  • Browse a set of random users as provided by soundcloud API
  • Browse a set of random groups as provided by soundcloud API
  • Add tracks to current play-list
  • Play tracks from play-list
  • Change song order in current play-list
  • Remove songs from play-list
  • Clear whole play-list
  • Start/stop/pause/resume songs
  • Control volume
  • Elapsed song time and current song-time are transmitted to clients

For a complete list of supported MPD commands see the implementation docs.

Quick Install Instructions

The following instructions describe in short, how to install "pyscmpd" on a raspberry pi with freshly installed raspian. For more detailed setup instructions see the next chapter.

Note: perform the following steps as user "pi".

1) Install missing debian packages

sudo apt-get install git python-setuptools python-gst0.10 gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly gstreamer0.10-alsa jackd ncmpcpp

2) Install soundcloud python API

sudo easy_install soundcloud

3) Install pysmpd

mkdir $HOME/src
cd $HOME/src
git clone
cd pyscmpd
sudo python install

4) Autostart pyscmpd with the desktop

mkdir $HOME/.config/autostart
cp ./etc/pyscmpd.desktop $HOME/.config/autostart/.

5) Run daemon, connect to it

pyscmpdctrl start
ncmpcpp -p 9900

Detailed Install Instructions

On Debian Based Linux Systems (e.g. Ubuntu, Respian, ...)

For the following steps, it is assumed, that $HOME/srcis your working directory:

mkdir $HOME/src

1) Install soundcloud-python

apt-get python setuptools:

sudo apt-get install python-setuptools

clone the sources:

cd $HOME/src
git clone

run the setup script

cd soundcloud-python
sudo python install

Note: Internet connection is needed for this step, since the installer will go and fetch some dependencies from the net.

2) Install python-gst and dependencies

apt-get the library:

sudo apt-get install python-gst0.10 

on a fresh Respian, I needed additionally the following:

sudo apt-get install gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly gstreamer0.10-alsa jackd 

3) Install pyscmpd

clone pyscmpd sources:

cd $HOME/src
git clone 

install pyscmpd:

cd pyscmpd
sudo python install

3.1) Optional: autostart daemon with LXDE

If you like to start "pyscmpd" with your LXDE desktop on a raspberry pi, you could create the file "pyscmpd.desktop" under "$HOME/.config/autostart" with the following:

[Desktop Entry]
Comment=Python based soundcloud player using the MPD protocol
Exec=pyscmpdctrl restart 

Next time your desktop is started, "pyscmpd" will also be started.

4) Get a decent MPD client

I prefer ncmpcpp:

sudo apt-get install ncmpcpp

Or for a GUI based client sonata:

sudo apt-get install sonata

On Other Linux Systems

To be done ...


In the main directory start "pyscmpd" daemon with:

pyscmpdctrl start

A default configuration is created under "~/.pyscmpd/pyscmp.conf". To change the port (default 9900), logging, or favorite users to browse change this file.

By default, the log output of the daemon could be viewed by:

tail -f ~/.pyscmpd/pyscmpd.log

Now you should be able to connect to the daemons default port 9900, e. g. with ncmpcpp:

ncmpcpp -p 9900

To stop the daemon use:

pyscmpdctrl stop

In case "pyscmpdctrl" complains about the PID file already existing, and you are sure the daemon is not running yet, you could use the following command to cleanup the PID file:

pyscmpdctrl rmpid 

For debugging, it may be useful to start the daemon in foreground. This could be done by:

pyscmpdctrl --foreground start

By doing so, log messages are printed to "stdout", while the log-file specified will be ignored.


To modify the list of your favorite users to browse, edit the "[favorite-users]" section in "~/.pyscmpd/pyscmp.conf". The format used for favorite users is:

category: user1, user2, ...

category is then shown in the browser as subfolder folder of "favorite-users" folder, containing all the users specified. userN is the user name of a soundcloud user as shown in the URL. E.g. "griz" for GRiZ.

To define the favaorite groups shown in the browser, add them under the "[favorite-groups]" section in "~/.pyscmpd/pyscmp.conf". The format used for favorite users is:

groups: group1, group2, ...

groupN is shon in the broser as subfolder of the "favorite-groups" folder. groupN is the group name as shown in the URL when browsing a group. E.g. "deep-house-4".

The following shows a complete sample for the two mentioned section as seen in pysmpc.conf:

ghettoswing : maddecent, barelylegit
electrosoul: griz
deep-minimal-house: grumoh
tech-house: beatkind, atmosphererecords

groups: deep-house-4, minimal-tech-house, swing-fever-electroswing-group, ghettoswing-and-swingstep

NOte: Each time "~/.pyscmpd/pyscmp.conf" is modified, the daemon needs to be restarted by:

pyscmpdctrl restart

Note: an example configuration could be found in the project directory under "./etc/pyscmpd.conf".
