Being new to the software I mistakenly thought that I could copy files from the various paylists and 'soup' all willy-nilly and the system would weed out duplicates. I now have one dump playlists with over 16,000 titles listed (mostly duplicates) Yes, yes, insert derisive laughter here. So I tried to deleting all of the songs from the playlist but after it sat for 3 hours I gave up. Then I tried to just delete the playlist itself, again, it appeared to lock up. So my question is this. Is a huge wait-time to be expected when deleting such a large playlist? or is there a down and dirty way to get rid of it all.

I know better now.
