Missing portion of an album
I had purchased the Album "America's Greatest Hits: History" several years ago. Now, only one song shows ups in it. The more concerning issue is that when I search the album in the iTunes Store that song is the only one that shows up in the album there. The description of the album mentions all of the other songs, but they are not there. It does show I purchased it and I paid full price, so I am not sure where it went. There are no hidden songs/albums, and I checked on my MacBook and iPhone which are both fully updated.
