*IMPORTANT*
Since the coverflow component is still in early beta stages, I strongly recommend taking a full backup of your foobar folder, before you use it. Also make sure you're running the latest drivers for your graphics card.
Get the latest version for foo_bubble_coverflow from [link]

Your songs should be properly tagged in order to use this config as intended
The cover art must be named folder.jpg and be located in the same folder as the music files.

*To install*
copy the contents from the component folder to your foobar2000/components/ dir, overwrite older components if needed, copy the UnitedColors.pui file to foobar2000/PanelsUI (create PanelsUI dir if not already present) open foobar.. open the preferences pane.. go to diplay-PanelsUI choose UnitedColors as your config.

*Update
Updated to include a seekbar and playlist swithcer(removed the alternate playlist)
You need to set up the playlist switcher to use the same colors as the config.
