Matched songs play on all my devices but not on my iMac
I have iTunes Match, some songs that have the iCloud status as matched will play on my iPhone, Apple TV and iPad, but will not play on my Mac. they either play for about 10 seconds then stop or won't play at all. I've updated iCloud library, I have synced libraries and all devices are signed into the same account, they are all using the same internet connection. Even if I download the track it still won't play. (on Mac). Most songs play fine, but quite a few don't.
