Hey Joey C 2,
If I understand correctly, you want to sort the music in your library by year. You can sort the music a few different ways. I would recommend you use this article for more information.
"Your music is sorted by up to five categories (Genres, Composers, Groupings, Artists, and Albums), divided into columns. As you select an item in each column, the list narrows down to display only the matching songs."
Customize the iTunes window on Mac
Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.
