This article isn't entirely clear HOW it will be integrated; i.e., as a stand-alone app or part of iTunes or Music app. Does iTunes Radio get relaunched as Beats? I just can't see Apple packaging 3 music apps with iOS. Sounds like a Rube Goldberg contraption. That's the epitome of "unsimple."
If you've imported your own TV show (like from your DVDs) into iTunes lately and tried to set the "common" metadata items (show, episode name, season, episode, year, artwork) you'll know that 3 music apps is nothing. They are just getting started.
