Apple has hit a significant snag in their quest to bring their long-rumored "iRadio" streaming music service to market. Despite signing Universal Music, Cupertino has been unable to complete deals with Sony Music and Warner Music, according to The Financial Times. In April, Apple looked all but certain to be nearing streaming music deals with each of the three music labels. However, some are now balking at Apple's latest offer, believing that by holding out they could get more. It is believed that Apple has offered a royalty of about 12.5 cents for every 100 tracks streamed. This offer is in line with the rate paid by Internet-radio service Pandora, and more than double what Apple had originally wanted to pay. Some music executives believe that Apple should pay a higher rate than Pandora, because of their broader ambitions for iRadio.
