I bought a stand-alone single from iTunes a few months back. The single was released as its own album since the rest of the album wasn't released yet. Then I bought the whole album a few months later when it debuted. The only problem is that the album has 20 songs, but I only have 19 of them on the album and I have the remaining single as its own album. I selected the "Complete My Album" option but now the main album has songs 1 through 15, skips 16 (which is the single I bought), and goes from 17 through 20. If I want to listen to the single, I have to get out of the current album and go to the single (which has its own album). How do I fix this? Unless I have to manually buy the song again from the album and make two purchases?
