Citing people familiar with the ongoing talks, Apple inked a deal with Warner Music Group over the weekend for both recorded music and music publishing rights, adding to an existing arrangement with Universal Music Group for recorded music, reports The New York Times.
The sources claim Apple is working hard to reach amicable terms with some of the world's largest music labels ? Warner, Universal and Sony ? so it can present iRadio at WWDC, which kicks off on June 10.
Apple was first rumored be working on an Internet radio service in September 2012, but has reportedly hit snags along the way as music publishers continue to demand unacceptably high royalty rates and minimum payments. A report earlier this month claimed Apple's unwillingness to pay royalty advances to copyright holders has kept the company from striking deals with the three major labels.
Most recently, the company was said to be offering a hybrid payment system in which both royalties per track streamed and a share of iRadio's advertising revenue would be doled out to publishers. Also on the table is a guaranteed minimum payment, though exact numbers were not reported.
According to Sunday's report, iRadio will be mainly ad supported, much like popular Internet radio services Pandora and Spotify. It is unclear if Apple will offer a "premium" subscription tier to remove ads and boost revenue. Also in the cards is a possible tie-in with iTunes, which would offer users an easy way to purchase tracks heard on iRadio.
While iTunes dominates online music sales, Apple will be a late entrant to the Internet radio sector as even Google joined the fray with its recently released "All Access" subscription service.
WWDC 2013 is scheduled to run from June 10 through 14 at Moscone West in San Francisco.
