Unkown media taking lots of space on iPad

Have an iPad Air that is only 16 GB but usually good enough to download 2 movies to watch coming and going on the plane. There is really nothing else on the iPad other than the stock apps yet when I go to storage I have 14 of the 16 GB used and a big portion is media looking at the bar. I checked the TV app and Itunes but all my previous rentals are gone. Anyone know how to remove this mystery media and free the space back up?

Hi, Brett!
I found an inordinate amount is being used by the apple iPods app to the tun of almost six gigabytes. Call Apple Care– they’ll help you.
