I just switched from Amarok 2 to Songbird, I tried it many times, but not until 1.4.3 did I find it stable and usable and have all the bugs kinked out that made it me want to switch to use it across me windows, linux and osx machines, only to discover that the next day the dropped linux support. My fav. player to date has been Foobar2000 but thats windows only any cross platform music players anyone would like to suggest. I know amarok is working on a osx and windows version.....

pulseaudio?? I installed it before it was the default sound daemon in ubuntu and have had very minor issues, the only issues experienced were with flash, which was quickly resolved and networked audio over wifi, which seemed stutter but over Ethernet sound was perfect.

Just tried to use the demo, got an invalid username and password, so far it more secure then the actual OS....
