ITunes For Mac :: New Album Downloaded / And 1 Song Is Not Authorized To Play

I just purchased an album from iTunes.  All songs play except 1.  When I attempt to play the fourth song, I'm presented a dialog box telling me that I'm not authorized to play the song on the same computer I used to download it.  When I enter my Mac ID and Password to authorize the song, I receive another dialog telling me that the song is already authorized to play on this computer.  I attempt to play the song, and once again informed that I'm not authorized to play the song, going on to state that I've only authorized two out of the five allowed.   

I've gone into my Mac account, and only three devices are authorized (Mac, iPhone, iPad).  I went ahead an removed authorization on this Mac, then re-added my authorization.  Still, the same song out of 20 will not play due to authorization.
