Why does iTunes continually ask me to authorize the computer

itunes

I just recently bought an album on iTunes and I have a weird problem. All of the songs (18 in all) except for one, play perfectly fine. When I try to play it, it says "This computer is not authorized to play "". Would you like to authorize it?" It prompts me to sign in with my Apple ID, which I did. Then it says "This computer is already authorized." I have no clue how to fix this! I've tried the steps outlined in iTunes: Missing folder or incorrect permissions may prevent authorization and iTunes repeatedly prompts to authorize computer to play iTunes Store purchases, but neither of them work. Any suggestions?

In the end, deleting all the offending track and re-downloading it was the only thing that worked. Why I didn't think about this at first, I don't know, but it worked!
