Macbook Music app is not making playlists properly
I have audio book CDs that I have been successfully importing into my Macbook Pro 2021.
It's been working great until recently.
I would simply insert the CD, and Music would see the tracks on the CD.
Then I would drag them into a new playlist on the Macbook, connect my iPhone 13 and they would sync to the phone just fine.
Recently Music would put all except the last track onto the new playlist I had created.
So I can't get the whole CD into the playlist on my Macbook. Even if I try and drag the last track on manually.
I think something is corrupted with the Music app on my Macbook.
Is there a way I can delete the Macbook Music app and reinstall it, or force a repair in some way?
I really don't want to wipe my Macbook and reinstall all apps. It would be too disruptive to my work life right now.
What can I do?
