Apple’s Online Radio Service to Challenge Pandora in 2013
I'm not sure why Apple would want to get into the streaming music game. It's expensive, and it would pretty much obliterate a chunk of their download business, so I hope they've done the math.
Lot of musician-types I know personally are hoping that Apple will offer to pay more in royalties than Spotify, Rdio and other competitors. It could happen, and it wouldn't be the first time Apple has offered more favorable terms to "content creators" in order to put the screws to their competition.
I don't think they'd have to, though. I suspect a streaming iTunes would be an instant success, so why pay a bigger bill if you don't have to? Guess we'll see.
