Amarok 2 has been released. I drooled over the the pre-release incorporated in Mandriva 2009 (but without actually running it). Having installed it on my Ubuntu system, yes, it still looks wonderful. Not sure about the current state though! There's some screenshots here. There's various spiffy new features, but I'm rather attached to some of the old ones - like playing cd's I don't want to always have to rip the cd first - I'm hopeless at deleting the files afterwards and it does fill my work laptop up. And then there's stopping after the current track - I want to finish listening when the current item is over and not now!
For the moment I'll be sticking with amarok 1.4 but maybe peeking a look at the new interface now and then!
