AllThingsD reports today that Apple has successfully concluded negotiations with Sony regarding the issue of iRadio. iRadio has been rumored to be unveiled at WWDC 2013, and this most recent report would back up such rumors.
Sony was the final major label that Apple had to sign in order to offer iRadio with a full library of music. Both Warner Music Group and Universal Music Group, the other two major music labels, were signed earlier this year.
iRadio is supposedly more of competitor to Pandora than to other streaming solutions, such as Rdio or Spotify. An ad-supported version of iRadio is also on track for a WWDC unveil.
