Songbird is a desktop media player mashed-up with the Web. That means that you can also browse the internet with Songbird, that’s built on the firefox platform.
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.
