I can only assume some kind of corruption in the library xml file, though it appears to have been totally random. Not all the track references have been duplicated, only some artists and not complete albums. None of the duplications are tracks that are synced to my iPhone.
I have a special setup - I use my iMac as the main storage location for my music. This is synced to a Macbook which I use for DJ'ing.
The sync application is called FileSync (http://www.macupdate.com/app/mac/23023/filesync). All it does is copy changes from the iMac to the Macbook and therefore should not affect the iMacs library in any way.
The situation now is that since I have a synced copy of my library I have a duplicate issue on the Macbook. So if you wanted to examine the problem you can.

the library XML file is a file that iTunes does not read - it
only writes it for other apps to read. beaTunes is one of them. So
if there is wrong info in the XML file, it must also be wrong in
the actual iTunes database.
Can you please email me the iTunes Music Library.xml file from
your MacBook along with the name of one of the songs that is a
duplicate entry, but not a duplicate file? I'm just curious to see
what the entrie in the XML file looks like.
Regarding the issue itself, I'll put some logic in beaTunes 3 to
work around the issue.
