Songbird is an open-source customizable music player that's under active development.
NEW FEATURES AND IMPROVEMENTS
On Demand Fetching of Album Artwork
Songbird can now fetch album artwork from the web at your command. Simply select or right-click a track and choose "Get Album Artwork". You can also select your preferred source of artwork. By default, Songbird will retrieve album art from Last.fm but you can install from other sources such as amazon.com via an add-on.
MTP Device Support
We fixed many bugs affecting MTP devices on Windows. We've also added the ability to synch authorized Windows Media DRM'ed content to your MTP device. To see if your MTP device is supported, or to report your findings, visit our MTP Device Support page.
You can choose to watch a folder hierarchy for changes and the content will auto-magically be imported in your library. If a file is removed from the watched folder, the corresponding track will be deleted from your Library.
Library sorting supports unicode collation and better handling of leading definite and indefinite articles such as "The" and "a".
Replay Gain Support (Normalization)
If a track's metadata contains replay gain (including iTunes-specific) information, Songbird will adjust the playback gain appropriately.
Reduced Installer Packages
We've reduced the installer package size on Mac and Linux by about 45% on each of those platforms.
Improved Memory Usage/Performance
As part of our project to bring down memory usage in Songbird, we've re-tuned the database to be less greedy with your system's memory. On some memory starved systems, this should actually increase performance, but most users shouldn't notice any difference in searching, sorting, scrolling, filtering, or smart playlists. Users with very large libraries (>100,000 tracks) will see the biggest memory use improvements. If you do find things are more sluggish than you remember, please see Tuning Songbird Memory Usage and try adjusting the page cache size upwards. If you find any problems in these areas, please file a Bugzilla issue against Songbird.
7digital MP3 Store Add-on (Beta)
We've partnered with 7digital to bring you the highest quality MP3s (320kbps). You can easily search, purchase, organize and get recommendations directly into Songbird. Just click on the 7digital Music Store node in your Songbird service pane. NOTE: The UK store is fully stocked, but the US and other European stores are still continuing to populate a complete catalog of music. Please file any bugs, issues or suggestions for the 7digital MP3 store specifically in our Bugzilla database.
