Hey, remember the open source app Songbird? Well they remember you, and are backing this up with an app that is ready to roll cross platform.

Eager birdbuilders, you may now build the bird.

Songbird’s public Subversion tree is open. Initial build instructions have been posted to the Songbird Trac. Developers may download the source via HTTP or BitTorrent. Please report bugs and post patches to Songbird Bugzilla.

Note that this our not-yet-0.2 source code release, which means it is not yet our 0.2 “Developer Preview” release as defined in our Songbird roadmap. The internal birdbuilder team will be substantially changing numerous APIs between now and the 0.2 launch. Eager Songbird extension authors should wait for the 0.2 “Developer Preview” launch.

Finally, Songbird not-yet-0.2 binaries are available for Windows XP, Mac OS X and Linux. We’ll frequently update the binaries to
reflect the latest source changes.

Build the bird, play the Web.
