Songbird
A Web player built from Firefox´s browser engine 
Songbird can do everything you'd expect a media player to do. Play music from your computer, as well as from the Web in one integrated user experience. If you run a music service, you can leverage Songbird's APIs to create deeply integrated stores and user features.
Play any MP3 on the Web without leaving the page. Songbird can view Web pages as dynamic playlists that it can play, save, or automatically download every day.
Songbird plays your music too. Songbird has all the features you expect in a desktop media player. And Songbird constantly improves. Like Firefox, Songbird's features may be improved with user installed and contributed cross-platform extensions.
