Songbird 1.0 released
The cross-platform music player comes in Mac, Windows, and Linux versions, and can handle playback of most music formats. Like most Mozilla-based software, Songbird supports plugins, including a QuickTime Playback plugin that adds the ability to play music purchased from the iTunes store. There's also a plugin that allows you to sync your music with portable media players including an iPod.
Songbird is much more than a music player. It's also an online music browser. You can visit web sites using the built in browser and automatically stream or download MP3 music from those pages. And thanks to the Last.fm integration, you can get additional information about songs and artists you're playing, or stream related songs from Last.fm.
