Purchased an album on iTunes. One of the tracks won't play. I get the pop up authorization/ password box-This computer is not authorized to play "Dust To Dust". Would You like to authorize it?
Then blah blah about 'you need to authorize this computer, you can authorize 5 computers'.

Tried on my iPhone, the song just doesn't play, skips to the next song. It's only the one song. First time this has happened that I can remember.

I have found on occasion that you have to de-authorize then re-authorize to solve this!
