You realize that iTuns has no concept of "albums" as an entity, right? I mean, yeah, you've got cover art for your songs, and you've got album names, and you've even got artist names. But, what's the cover art for an album? Who's the artist for an album? Do you just pick one from the various songs which happen to share the same album name? Or would you want iTunes to be doing a binary-blob diff on the cover art for each song and show a list of all unique images (even if one "album name" has four different cover arts, or three "album names" all share the same cover art)?
It's "doable", but I wouldn't call it "simple". There are some hard design decisions to make, and even then you won't be making more than half your customers happy no matter which way you go!
