Music on iMac won't automatically advance to next song or movement
When playing a music album, Music will not automatically advance to next song or movement
Jay,
That symptom usually means that your songs have come unchecked, since Music will not automatically advance to an unchecked song. Make sure you are in Songs view and look at the checkboxes next to the songs. (If you can't see the checkboxes, go to Music > Settings > General, and enable "Show -- song list checkboxes.")
