Apple deleted my backups from icloud, my win7 laptop, and all copies made on flash drives. I had successfully backed up music not purchased on itunes for years but now Apple says, "Oops, sorry. Just use apple music" How can I restore my music? I'm not paying for apple music and my cds were stolen last year so I cannot reload.
