Firefox for Music?
Using the technology from Mozilla’s Open Source movement, a new media player is set to hit the market. It’s called songbird and it well… looks just like iTunes. Being open source though, suggests there will be much more room for growth and improvement, not seen in the tightly locked down source of Apple’s iTunes.
Songbird’s underlying programming technology is called XML User Interface Language, or XUL. Along with letting people create their own look for the software, this will allow music services or developers to write their own plug-ins, letting them add features or tap directly into their own digital-download stores.
