Missing 'Opiate' song from Tool's Opiate album on iTunes

The Song Opiate from Tool’s album Opiate is missing. When I go music purchased section in the iTunes Store, it shows every song but Opiate.

But if I search the iTunes Store and go to the album, all of the buttons that once displayed the price of each song read “play,” except the one for Opiate. It reads “purchased.” So, it’s not like I can just buy it again.

And no, I don’t have it backed up anywhere.
