Thank you for your reply.
They are all on my local drive. I have a mix of purchased through iTunes Store and songs I've pulled off of purchased CDs. I've burned CDs from my playlists within the last 8 months and haven't had this problem.
I hope Apple is not pulling the plug on tunes I purchased from either source.
The only reason I even burn CDs is because my 09 Murano Bluetooth is way out of date and don't want to spend the money to have it updated at the dealership. It's over $250. It won;'t work with the latest iPhone bluetooth in my iPhone 5 on up. Now I have an iPhone 8+.
I used to be able to play my iPod in my car but something even went wrong with that. Bought a new cable from a 3rd party Nissan factory parts resource ($56.00) and the cable didn't work. They wouldn't take it back.
So…I don't know what's wrong.
