SongBird Browser

Songbird is a desktop media player mashed-up with the Web.
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, to wit, an Open Media Web.
