Amarok generates library information from tags stored in files. If you've stored you iTunes library in WAV format, those tags won't exist, and Amarok won't import any of the songs.
This tool reads the XML-formatted iTunes library file, and loads the data into Amarok, giving you full access to you music through Amarok's user interface.
