The publishers and content holders have fragmented the market so that you can't purchase your song, tv show, or movie in the media (cd, dvd, bdrom, download, stream), or stream provider (netflix, hulu, apple, HBO, showtime, etc) without subscribing to multiple providers or buying multiple copies. And they wonder why users pirate content.
This is just another example, if true, of wanting something for nothing. Sony expects Apple to pay for someone who doesn't listen to a song. As many have said, Apple should just say - "Thank you, have a nice day. Come see us when you ready." And release it with the other labels. Call their bluff and see who has the egg on the face at the end of the day. Particularly if you run an ad letting the listener know that is why they can't hear a Sony artist.
We don't know what the feature set is going to look like on iRadio, anything we guess is just that - GUESSES!
