New iPhone XR won't stop asking me to log into random Apple IDs?

I got a brand new XR yesterday and I was filling it with my iCloud data when I got a popup message saying "Sign into iTunes store. Entire the password for your Apple ID: " but it was a random email address that I d never heard of. I clicked cancel, then it happened again, and again, and again at least 100 times.

I have some music on my iTunes that was illegally obtained (someone else bought it and then uploaded it) and I then realized that these emails were the emails of the people who bought these songs/albums and uploaded them for free download. After 10 minutes or so, the popups stopped only to happen again this afternoon and now again in the early evening. I know it's not ethical but I have so much music in my iTunes from these emails, so is there any way to stop these popups without deleting my music?
