I have a perplexing problem regarding just one of my music files not being recognized by iTunes. I like to make my own albums of artists and in this case I want to add the Beatles' Don't Let Me Down to the Let It Be album, but after making the necessary changes, i.e. changing the album title from the Past Masters album to the Let It Be one, etc., it does not go into the Let It Be Album (it does show up in the list of songs with Let It Be as the album but when you click on either Artists-The Beatles-Let It Be or Album-Let It Be, the song is not listed) I've done this before with other songs and albums with no problems. What happens in this case is when I try adding the Don't Let Down file, it creates a new Beatles directory and a new but separate Let It Be album with just the new song in the album. The file plays through so its not corrupted. How can I get iTunes to put the Don't Let Down file into the established Let It Be album? Thank you in advance for any insights and help.
