These notes show (which are mostly for my benefit) show you how to install it and configure your multimedia keyboard so the play/pause key controls the music on Spotify.

Download Spotify for Linux. It's available in 32bit or 64bit.

Double click on the .deb that has been downloaded and it should install. Nice and easy!

To get the multimedia keys working, we need to follow the instructions in this tutorial and the codes described at lnxscene.

Install xbindkeys.

sudo apt-get install xbindkeys

Create the default configuration file for xbindkeys.

xbindkeys --defaults > ~/.xbindkeysrc

Edit the configuration file for xbindkeys.

nano ~/.xbindkeysrc

Add these lines:

"dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause"
XF86AudioPlay
"dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Stop"
XF86AudioStop

Run xbindkeys to see if it all works

xbindkeys

Now, when Spotify is running, pressing th eplay/pause key will make your music start or stop.

You will need to set xbindkeys to run automagically on startup.

On Ubuntu, System -> Preferences -> Startup Applications.

Done!
