Hello Linux Geeksters. As you already know, an Ubuntu skin for Spotify has been created.
If you do not have the Spotify client installed, this is how you install it on Ubuntu 13.04 Raring Ringtail.
To install the new Skin, just download it in the /opt/spotify/spotify-client/Data/ directory, like this:
$ sudo wget http://kurkot.us/spotify-skin/resources.zip -O /opt/spotify/spotify-client/Data/resources.zip
This skin was created by Juho ‘Kurko‘ Kurki.
