Update: Bloomberg adds more to WSJ’s report from earlier claiming that Apple’s new radio service will be tightly integrated with its iAd business. The report says Eddy Cue is currently making changes to the iAd business to support the new radio service scheduled to launch later this year alongside iOS 7:

We’ve heard no shortage of rumors on the rumored iRadio streaming service from Apple that has taken on some new urgency after Google released a similar service at Google I/O last month (and plans to launch it on iOS soon). The latest comes from the NYTimes, which says Apple is rushing to close deals as days wind down to WWDC’s kickoff on June 10th.

Apple also has cut prices so that media agencies can spend $1 million and use the purchased space for different advertising clients. And Apple started taking ad business from companies that sell alcohol, something Jobs resisted after creating iAd, said one person.

It would appear that Apple wants to announce the service at WWDC, but the company needs to overcome issues with closing some of the deals. CNET reported earlier today that Apple had closed the deal with Warner, one of the bigger labels.

In a strange irony, the music service Apple offers is, again, said to be free and supported by ads (like Pandora/Spotify/Slacker/etc). This is in contrast to Google’s service, which is sold via a paid subscription.

I would have guessed the opposite, but this may be why Google was able to close the deals with the labels and Apple is still at the table.

WSJ adds that Apple will pay Warner 10% of ad revenue, about twice as much as Pandora, and that the service will be integrated with iAd.
