Songbird uses Mozilla XULRunner and GStreamer media framework cross-platform frameworks. Songbird currently runs on Windows and macOS. In 2012, an Android version and an iOS version were released. Songbird at one point also supported Solaris and Linux, but this support was dropped. As a result, users forked Songbird and created a Windows, Mac, and Linux compatible derivative as Nightingale. Songbird announced on June 14, 2013 that it will stop all operations and close its doors on June 28. The company was unable to fund other activities and, as a result, all related operations and services were discontinued.
Users can add features and change the functionality of Songbird by installing extensions. Extensions are similar to extensions for the Firefox browser and can be easily ported. Community-encoded extensions are available on the Songbird addons support page. The known extensions of the community are: Qloud Tagging & Search, eMusic Integration, iTunes Importer, Artist Tracker, Library File Organizer, Audioscrobbler Notifier, Wikipedia Artist View, SHOUTcast Radio Directory, UnPlug, Adblock Plus, Metadata Manager Taglib, ChatZilla and FoxyProxy.
Skins are called “feathers” in Songbird, and give users and artists the ability to change the appearance of Songbird via an extension that generates a default skin. By using CSS (and possibly XUL), and an image manipulation program such as Photoshop or GIMP, users are then able to make Songbird look like they want.
Songbird was founded by Rob Lord and developed by Pioneers of the Inevitable (with members who have already developed both for Winamp and the Yahoo Music Engine). In January 2010, Philips announced the shipment of a custom version of Songbird with part of its range of portable audio / video players. On April 2, 2010, it was announced that official Linux support would end with Songbird version 1.7.2. POTI Inc. would instead focus on its Songbird Windows and Mac OS X versions, providing only unofficial support for Linux versions. In late 2012 or early 2013, Songbird’s public SVN was removed, along with their wiki and other source code utilities. A poll sent later on Twitter by Songbird suggests that POTI closes the desktop reader’s source code, planning to later sell an updated version, fixing many bugs and feature requests by users who have been skipped for years.
