While Apple has yet to confirm its rumored cloud-based music service, details have come out highlighting its finer features. It is speculated that the new service from Apple is supported by EMI, Sony, and Warner Music, three of the “Big 4” music labels, leaving Apple one signature away from the full support of the music industry. It is also reported that the service will mirror the user’s entire iTunes library and support streaming from the Internet to a range of devices, allowing music lovers to listen to more than what they can store on their gadget. While the ability to stream your music collection to your iPad or iPhone will certainly be cool, it almost certainly will not be free. It is highly likely that Apple has paid a pretty penny to obtain the cloud music licenses, and it is not clear how much of those costs will be passed on to users.
