Last month, that was talk that negotiations with Sony and Warner were holding back the launch of the service. Now, with Warner in the fold it apparently is all up to Sony to sign on the dotted line to get the music playing. According to those familiar with the negotiations, Apple gave Warner everything on the publishing end that it and other publishers were seeking, which is 10% of ad revenue. That is twice as much as the amount that Pandora pays and could set the the groundwork for new contracts once the current ones expire.
According to insiders, the talks with the music publishers have dealt with royalty rates, a minimum guarantee in case Apple decides not to run ads right away, and a point when ad revenue is split. Apple's deal with Universal covers songs, not publishing, and Apple remains far apart with Sony. Sources say that without inking those two deals, Apple will not launch the service.
