Song won't play on my iMac but will on other devices
I paid for/downloaded 2 songs from iTunes. Both songs are by Tammi Neilson.
One song plays on my computer, my iPhone and my iPad.
The other song (Ten Tonne Truck) will play on my iPhone and my iPad but not on my computer. When I try to play it on my computer I'm warned "You must authorize this computer before you can use Apple Music or iTunes Match on this computer" pops up. When I attempt to authorize the computer I'm warned I've exceeded the number of computers allowed. Only my iPhone and my iPad (meaning 2 devices) show as authorized. No one else shares my music library. So: why doesn't Ten Tonne Truck play on my computer when it does on my other devices? Any why can't I authorize my computer?
