As a result, users forked Songbird and created a Windows, Mac, and Linux compatible derivative under the name Nightingale.

Known community designed extensions are: Qloud Tagging & Search, eMusic Integration, iTunes Importer, Artist Tracker, Library File Organizer, Audioscrobbler Notifier, Wikipedia Artist Display, SHOUTcast Radio Directory, UnPlug, Adblock Plus, Taglib metadata handler, ChatZilla, and FoxyProxy.

Using CSS (and optionally XUL), and an image manipulation program such as Photoshop or GIMP, users are then able to make Songbird look however they want.

POTI Inc. would instead focus on its Windows and Mac OS X versions of Songbird, providing only unofficial support for Linux releases.

A survey later sent out via Twitter by Songbird suggested that POTI was closing the desktop player source code, planning to later sell an updated version, fixing many outstanding bugs and feature requests by users who had been ignored for years.
