In any case count me out. I'm on the brink of dumping Apple for all music. I hate things on principle that feel like they're designed to "guide me" toward a desired "consumer behavior."
I also hate what this does to music. Music isn't meaningful in this model. It's a formless uniform commodity that you consume on demand. Maybe that works for disposable pop that all sounds the same but not for music you care about.
This is definitely why. It's also why Apple barely pays attention to the iPod line and hasn't shown any interest in making a large storage device like the iPod classic (which I foolishly sold!).
The really confusing/annoying thing for me is there's no history AFAIK. So no looking up the previous song if you didn't get to hit the heart button because you were driving. Even finding a previous streaming/radio playlist is impossible sometimes. Click away from it, and now how do you get back? On the iPad: You don't AFAICT. Best you can do is bring up the Up Next list if you don't remember the search/navigation that found the playlist in the first place.

I assumed it was just a "genius" thing at first as well, but there they are. Maybe it's new.
And wow... Discoverability--
Streaming? Just treat it as a playlist. Remember a song off a stream? Make that be like an adhoc playlist. Just let me mash a button and play music. Let me hit a button, and it remembers the current song. Want to let me pick a stream? Let me navigate just a few steps down a menu and pick something. Hit play. Music. Done.
