Music unavailable for download

I purchased the 5 songs from the Scotty McCreery Christmas album at least a year ago, I removed all my Christmas downloads from my device for the summer. Now when I go to my purchased songs only 4 of the 5 show up. I was able to download the 4. When I search the album in the store, the 4 songs show “play” and 5th song shows “purchased” but I can’t download or play it or even find it in my purchased song list. The missing song is “Christmas In Heaven” by Scotty McCreery.
