Apple pushes to complete music licensing deals after months of delays.

The New York Times reports that Apple wants to unveil the streaming Internet radio service, nicknamed iRadio by the press, at its developers conference, which begins on June 10. However, talks have stalled as record labels and music publishers are seeking higher royalty rates and guaranteed minimum payments from Apple.

Apple has signed a hodgepodge of incomplete deals: it has a deal with Universal for recorded music rights, but not for publishing; it has a deal with Warner for both; it’s still in talks with Sony’s music and publishing arms. The music companies allegedly see “promise” in Apple’s service, because it would be linked to iTunes, but are seeking 10% royalty rates from Apple rather than the 4% rate that Pandora pays.

First announced last year, the streaming service is expected to be free to use, compatible across all of Apple’s devices, and supported by Apple’s iAd Network. Google launched their Google Play Music All Access service last month.
