Exciting news!
Amarok for Windows is coming. If you're not familiar with it, Amarok is only the single greatest media player ever created. Unfortunately, to this point, it has only existed for KDE/Linux.
Shane King however, has come to the rescue and started working on a version of Amarok for Windows. It's still very early going (and it's just one guy working on the Windows version at this point), but it's exciting nonetheless.
