I've been following Songbird since it's inception.
With excellent graphics, shwag, and a whizz-bang easy-to-use UI it was hook, line, and sinker. Oh and did I mention that the team includes some former Winamp coders? Well I did now.
The new release comprises a bunch of bugfixes and improvements - too many to list here.
