A Firefox for music?

[Techconnect] If digital-music veteran Rob Lord wanted to court controversy with his new open-source start-up, he probably couldn't have done much better than to compare Apple Computer's iTunes software to Microsoft's Internet Explorer Web browser.
Lord's new five-person company, the ambitiously named Pioneers of the Inevitable, is building a piece of digital-music software called "Songbird," based on much of the same underlying open-source technology as the Firefox Web browser.

It would be nice to have a music player (or even better: a media player!) with the same quality and professionalism as the Mozilla Thunderbird and Firefox (in their own fields).
