With another great start , the ui as cool as the KDE4.x itself.
Though missing that blue colour, I specially liked the play menu buttons. Btw, remember to delete/rename the old ~/.kde/share/apps/amarok/collection.db file as the db schema changed. Now if you want you can undo/redo tracks added in the playlist. You can use middle click on the system tray icon to play/pause. Need to play around some more time to understand the other new features. A screencast is on due for this.
