I bet you dont believe me!
Above is actually rhythmbox. No really. So how did I do that?
In coverart-browser, select the *Flow* button, choose Coverflow (Vertical) from the Properties Button – Browser Preferences.
Make sure you’ve selected the black background and use the custom source-bar. Finally lets lose the unwanted side-pane from Rhythmbox by pressing F9.
Actually, the customisation options are extensive – so you can tinker all that you want to.
How to install:
sudo add-apt-repository ppa:fossfreedom/rhythmbox-plugins
sudo apt-get update
sudo apt-get install rhythmbox-plugin-coverart-browser rhythmbox-plugin-llyrics
