My wife built a playlist, not a smart playlist, in iTunes that is behaving strangely. For all our other playlists, I have no problem rearranging the order of the tracks by dragging and dropping the tracks where I want them on the list. However, when I try to do this for this one playlist, when I drag and drop a track, it just jumps back to where it was. I can't move any of the tracks. Of course, I tried closing iTunes and starting it back up again, as well as rebooting. I'm using the latest version of iTunes with the latest version of OS X. Any help would be greatly appreciated.
