Songbird is a music player built from Firefoxâ€™s browser engine. It is open source and runs on Windows, Mac OS X and Linux. Songbird plays the media web. Play MP3s without leaving the page. Songbird views Web pages as dynamic playlists to play, save, download or subscribe to. Songbird plays your music too with all the features youâ€™d expect in a desktop media player. Like Firefox, Songbirdâ€™s features may be improved with user installed and contributed cross-platform extensions. The release notes can be found here.
