Submit feedback to them if you want them to know this. They do not reply to all feedback but they do read it. http://www.apple.com/feedback will display links for each product's feedback page given the product in question has a feedback page. If this is about iPhoto go to the iPhoto feedback page, or if its iTunes -- there are 2 pages for iTunes Store feedback to request new content and iTunes app feedback. The iTunes Store feedback page is called iTunes Request Music.

For iTunes app go to the iTunes app feedback page or iTunes feedback page (should not say Request in the title).

Can even submit feedback to iPod team.
