@azkidney57 , I have had several MRI's and every time I go for mine they will have ear phones with music playing loud (not to the point of hurting my ears)
and they would ask what kind of music I wanted to listen to. However, I understand not all machines are equipped with it, so I would recommend what @becsbuddy said. My mother was claustrophobic and they advised her to take a Valium which did help her. Try to think nothing but happy thoughts.
