The left sidebar provides quick links to bookmarks, downloads, your music library in an iTunes-style interface, and several music discovery Web sites to get you started. When you're looking at any Web site with MP3s available for download, Songbird will open a new window at the bottom of the main browsing pane. Double-click on a song to play it, and links on the right let you purchase the track from Amazon, iTunes, eMusic, and Amie St. They also tell you the format of the track--MP3 or AAC, for example--and provide a blog link for more info.
Songbird has a growing library of extensions, and support is slowly growing for those written originally for Firefox. Although it works on Windows 7, it doesn't yet have any Windows 7-specific features. Still, Songbird is more than stable enough to take flight for the music-loving, Web-surfing fanatic in all of us.
