LuckyLefty I'm pretty sure there are multiple methods but I use this one:
1. Go to "Songs" along the side bar of iTunes
2. Click "Plays" to make it your primary dropdown and all of the songs will sort in order of plays, like this: https://i.gyazo.com/118ed3bb99553787e13d8b6b54414066.png (notice how plays is bolded)
