The exported file contains playlists too. Each playlist has a list of all the FIDs it contains in order. It may not be 1NF but it is possible to generate the playlist tree in the right order from it.
The only way I can see of exporting in a 1NF form is to also export a parent to child mapping table that takes care of the many-many relationship.
Remember that the export is designed to give as much of the data as possible in the raw form so that people can write scripts, Access databases or even COBOL to convert it into the form they want.
