Songbird is a complete desktop media player or "jukebox" with a uniquely open approach to Internet digital media network services.
Songbird is developed by Pioneers of the Inevitable, a small, chirpy team of digital media innovators whose previous incubations include the Winamp 5 and Y! Music Engine media players and Muse.Net, a location-independent digital media network service acquired by Yahoo!.
Songbird is a desktop media player mashed-up with the Web. Songbird is committed to playing the music you want, from the sites you want, on the devices you want, challenging the conventions of discovery, purchase, consumption and organization of music on the Internet.
Songbird is a player and a platform. Like Firefox, Songbird is an open source, Open Web project built on the Mozilla platform. Songbird provides a public playground for Web media mash-ups by providing developers with both desktop and Web APIs, developer resources and fostering Open Web media standards.
Songbird is an open source music player that offers all the standard playback features along with media library management and more. It also includes several unique features, such as integrated support for mashTape (to download artist related photos from Flickr), concert ticket search (powered by Songkick), and integrated SHOUTcast Radio directory, support for last.fm and more. You can import your existing audio files into the Songbird library, which automatically organizes them into categories based on your existing audio tags. Other features inlcude custom ratings, dynamic playlists, customizable interface layouts, an integrated web browser and more.
