I just did this in 56 . The tag is called Playlist Size. It probably only existed after RMML was made for the Karma -- not sure what jEmplode that maps onto. It won't appear in your column list by default, so you need to right click on the column headers and select Columns then pick it from the list. That method worked though. Turns out I have 45 titles that have duplicates (I have 4 Mandolin Rains -- who knew )
