When you buy the full album from Apple with the extra features does that show up? Album Art I could see to a point but I copy in my own album art not what iTunes offers.
I'm sure the posters here mean no harm, but those excuses are b.s. The album art is displayed, fullscreen, while a song is playing so there's no reason not to display it in a smaller, cover flow format.
My comic book apps use a form of cover flow and it's really convenient, in addition to being pretty.
Apple should do this. Correction: Apple should have done this from the start.
