I have been using iTunes on my Mac for 4 years now without any problems at all. Recently, however, the iTunes DJ function has started misbehaving.
Instead of showing the 5 previously played songs, and 15 upcoming songs randomly selected from the playlist I have defined in the settings, it instead shows the 5 previously played songs, plus many more than 15 upcoming songs. In addition, the upcoming songs are not from the playlist, they are from about 7 or so albums, in album order.
I have changed settings, change the source playlist, restarted iTunes, rebooted the machine. All with no change.
Does anybody have any idea how to get this working again?
