"Purchased" playlist titles missing
Using Spotlight, I found that the songs weren't missing from my iTunes library, but they are no longer listed where they've been listed up till yesterday. As far as I know I haven't changed anything within the program. Is there any reason iTunes would take it upon itself to clean out the playlist?
