only on jailbroken Apple iPads, not on Apple iPhones which could mean that the streaming service would be made available to iPad owners only. You might remember that last October, Bloomberg knocked down Pandora's stock by 15% when it ran a story that an Apple music service would be starting sometime in the first quarter of 2013. Executives representing big names in the industry such as Universal Music Group, Warner Music Group Corp, and Sony Corp’s music division allegedly have met with Apple in Cupertino to talks about plans for the service.
Apple's iPod nano has had the ability to play FM radio and allow the listener to tag a song that he liked to later purchase it from iTunes. Tagged songs are marked with an icon. Functionality like this could be part of what Apple is planning. We will know by the end of next month if Bloomberg's report was right.
