iTunes syncing songs that haven't been played or changed since last sync

Thanks. I am currently syncing the entire music library so there shouldn't have been any change in the songs' status (i.e. they haven't been played on any device, the artwork wasn't changed, etc.). I just synced two of my devices and more than 50 songs were synced on each device, a few may have been played on one or more devices but the majority were Christmas songs which haven't been played in months.

Thank you! Although my situation was a little different, the 2016 solution helped me fix my problem. In 2016, the issue was fixed by clearing the "work and movement" data from songs that had originally grouped as classical music. The songs in my playlist that were resyncing weren't grouped as classical so the "work and movement" data wasn't an issue for me, however, it gave me the idea to try clearing the grouping field for all songs which seems to have solved my problem: I've synced three devices so far and after an initial sync to update the device, subsequent syncs show no unwanted resyncing. Thank you for your assistance!
