Unknown data in Apple Music

I noticed that my Apple Music has quite a lot of stored data that isn't related to the app and I wanted to find out how to either get rid of it or at the very least know what it is. It is not downloaded music as the attached image shows. I have no downloaded music in the app.

I tried to both offload and delete the app but nothing seemed to clear/delete the data. When I delete the app, the data still shows up in the Apple Music shortcut when I check the storage. Restarting the tablet did nothing.

Any assistance would be greatly appreciated
