What does Album Only mean?
Album Only means that a track on the iTunes Store cannot be purchased individually and must be acquired by purchasing an album.
While there are some scenarios where album-only tracks are appropriate, Apple requests that all songs are made available for sale individually.
How do I make a track available as Album Only?
To request that a track be designated as Album Only, edit the song’s territory rights in My Music in iTunes Connect and submit an Album Only Request Form through Contact Us.
• Choose to designate songs as Album Only
• Make exceptions for content providers that cannot obtain rights for every song of their album (for example, compilations)
When can tracks be marked as Album Only?
Tracks can be marked Album Only when:
• The provider does not have the rights to sell the song individually
• The content provider only has the rights to sell the track as part of an album (for example on soundtracks or compilations)
These requests are evaluated on a case-by-case basis.
When may Apple designate a track as Album Only?
Apple also sells tracks and albums in a manner that we believe works best and in accordance with our business practices. As a result, we may elect to mark certain tracks as Album Only.
Tracks that are over 10 minutes in length are marked Album Only on the iTunes Store unless the track has been defined as a "Partial Album."
What is a Partial Album?
If your album is available on the iTunes Store but the Buy button is missing on iOS, greyed out on macOS, or does not start a download, this is called a ‘Partial Album’.
Partial albums occur when the digital version of a playlist does not match the physical version. Another scenario is when the 'track count' field in the metadata XML delivered via Transporter is greater than the number of tracks on the playlist.
Finally, if an album with songs or music videos isn't marked "Cleared for Sale," the album will show as a partial album, and those songs will not display. Partial albums will not be available for streaming or sale on Apple Music or the iTunes Store.
