Cover art for music releases, primarily OSTs and singles. Generally referencing CDs but not always. The tag may apply to both real and "mock-up" images.
This tag is only to be used for the cover art itself. When the packaging for a CD or phonograph record appears as an object within an image, use CD case or record jacket.
"Album" is aliased to this tag. For books used to collect or display photographs, use photo album.
