Or maybe we're just comfortable with the mix in of apps and music? No, not me. Artist and Album are certainly just wrong. Don't know how they can make that legacy labeling generic across music/movie/application. Creator instead of artist, perhaps. And just leave album blank for apps and movies. Album doesn't serve a purpose for apps does it? The link doesn't appear to work.
