Songs disappeared from my iPad Pro 12.9 6th Gen Music playlists but are still in my iPhone 14 Pro Max

Songs disappeared from my iPad Pro 12.9 6th Gen Music playlists but are still in my iPhone 14 Pro Max. The Verizon Wireless cellular service plan I have includes Apple Music. When I clicked on account settings I noticed that mysteriously my husband’s email is populated, however he does not have a music account. When I click on his email address and sign into my Apple account, I still do not have access to my playlist songs. How do I remove and or delete my husband’s email address and restore my playlists on my iPad?
