I have a fairly large itunes library that I liked to keep organized. As my library grows, I sometimes have a hard time figuring out which of my songs I HAVE NOT assigned to a playlist. I am trying to find a way to create a smart playlist that would display all songs in my library that are NOT currently in another playlist. The only thing I can come up with is to make a SPL that say "playlist is not" every single one of my other PLs. Any thoughts?
