A friend of mine just sent me a link to Songbird. From the website..
Songbird™ is a desktop Web player, a digital jukebox and Web browser mash-up. Like Winamp, it supports extensions and
skinsfeathers. Like Firefox®, it is built from Mozilla®, cross-platform and open source.
After a quick test on my main Ubuntu desktop, I have to say that I’m pleasantly impressed with what they’ve accomplished. I’m not one to jump on a new media player bandwagon as they all seem bloated and mostly useless to me but the simple fact that Songbird runs on XUL via XULRunner sparked my interest. At first glance it appears to me like a well done mix of ITunes/Rhythmbox/Winamp. I will save any further judgment until 1.0 is released but from a quick glance, it has great potential.
