Michael Tunnell has created a nice Ambiance theme for Spotify which makes the Spotify Linux client integrate better with the Ubuntu desktop.
For those not familiar with Spotify, this is a music streaming service with comes with desktop applications for Linux, Windows and Mac OS X as well as iOS, Android, BlackBerry or Windows Phone. The service is available in a limited number of countries. More @ Wikipedia.
The Ambiance Spotify theme comes with Ambiance-like toolbar and colors, a better Spotify tray icon especially designed to look like the Ubuntu Mono Dark icon set (the default icons used in Ubuntu), along with other tweaks that try to give Spotify a more native feel.
Here's a screenshot in which I'm using the Ambiance Spotify theme in Ubuntu:
And below you can see the original Spotify for Linux theme:
How to install Ambiance theme for Spotify
1. To use the Ambiance Spotify theme, firstly make sure you've installed the native Spotify Linux client. Then, download Ambiance for Spotify from HERE (see the bottom of the post for a download button) and place the downloaded archive in your home folder.
2. Then, close Spotify and run the following commands to install the Ambiance Spotify theme:
sudo apt-get install unzip
unzip ubuntu-ambiance*.zip
sudo cp resources.zip /opt/spotify/spotify-client/Data/
After this, you can remove the downloaded archive as well as the "resources.zip" file from your home directory.
If you want to revert the changes and go back to the default Spotify for Linux look, close Spotify and then simply reinstall it:
sudo apt-get install --reinstall spotify-client
