Spotify – the popular streaming music service – has updated its Linux client with a few extra treats, part of which include some Mono-tastic tray icons for Ubuntu users.
To use Spotify for Linux you need to have a premium account.
Installing Spotify for Linux
Add this line to your Software Sources list:
deb http://repository.spotify.com stable non-free
Refresh/reload the list when prompted.
Open a terminal and add the repository key (this stops you being nagged when updating)
gpg --keyserver wwwkeys.de.pgp.net --recv-keys 4E9CFF4E
gpg --export 4E9CFF4E |sudo apt-key add -
Now proceed to install the following packages via the Software Centre or the Terminal:
sudo apt-get install spotify-client-qt spotify-client-gnome-support
