Recently Added
iTunes puts recently added albums, movies, or TV shows at the top of your library, so that you can always find something new to play.
You can change the frequency Recently Added updates or turn it off completely in the view pop-up menu. The frequency options are This Month, Last 3 Months, Last 6 Months, and Last Year. Uncheck the box next to Show Recently Added to turn it off.

Regards,
-Norm G.
