A few months ago, I pondered why there are so few albums with digital booklets on the iTunes Store. I had discovered at the time that Apple imposes their own page format, which is not that of CD booklets, adding an extra step in the production process for record labels.
Well I found out something else recently: why record labels don’t add digital booklets to older releases. The answer is interesting; it’s because they can’t. Apple won’t let them. If a label has uploaded an album to the iTunes Store and wants to add a digital booklet later, the only way they can do this is to delete the original, and create a new album listing with a new SKU. And if they do this, then purchasers will no longer be able to re-download music listed under the old SKU.
It’s kind of foolish; it should be drop-dead simple to add something to an album on the iTunes Store, but Apple’s system is so rigid that it’s impossible. So if you wonder why your favorite label hasn’t added digital booklets to older releases, you now know why.
