MusicBee whips it, and all the other Amazon 1.4 forks. I was a massive Amarok 1.4 fan, and I think MusicBee is the dog's bollocks. On Linux, you need to install via wine though. But it's rock solid. You need to go for the 3.0 release though - after that, drag ordering of files doesn't work in Wine. There isn't a compelling reason to use the latest version anyway.
