There's a whole flock of programs out there for playing and managing your music collections. But Songbird stands out as an open-source program based on Mozilla.

Version 0.2.5 is still a long way from version 1.0, but there's a whole slew of improvements in the latest release.

• Support for playback of Windows Media and Quicktime files with DRM
• USB mass storage evice
• iPod device
• Web library that includes a filterable list of all the MP3 files you've seen while surfing
• Fullscreen video in Linux
• And a slew of bug fixes

I guess support for playback of files with DRM is a necessity in this day and age, especially if you want to use Songbird's feature to import an iTunes library. But I usually like to keep my open-source programs and my DRM separate. You know, by not using anything with DRM at all.
Songbird is still a bit of a memory hog, but it should run pretty well on most modern machines. It may not be ready for primetime yet, but it's getting closer with every release.
