Thanks for the question. The following resource may provide an answer to your question:
I purchased an album on my iPhone, iPad, or iPod touch that contained a music video and a digital booklet. Where did it go?
Bonus items, such as music videos, will download directly to your iPhone, iPad, or iPod touch. Digital booklets are available in your download queue when you log in to the iTunes Store on your computer. Find more information about syncing digital booklets.
