iTunes Match Duplicates
I seem to have made a bad mistake by using my master iTunes collection Mac as the source for my initial iTunes Match account. I have 2 versions of ever song in that library, an AAC and an AIFF. Now it seems that iTunes Match has 2 copies of every song (Thousands). How can I eleminate all these duplicates in iTunes Match before downloading to my other devices?
