Leading up to the unveiling of Apple’s new iTunes Radio service earlier this month at WWDC, we reported on some small details regarding deals Apple had reached with the major labels necessary to get bring its Pandora competitor to market. Earlier reports claimed that Apple was paying Warner around 10% of ad revenue— that’s around twice as much as Pandora reportedly pays. Today, The Wall Street Journal provides us with some in-depth info on what Apple is paying labels and publishers after taking a look at the terms of the deal.

Apple will in fact be paying well over the 0.12 cents per listen Pandora offers the labels, as well as a percentage of ad revenue, and the payout will also increase during the service’s second year:

However, there are some exceptions. The report notes that Apple won’t have to pay royalties for songs that users already have in their iTunes library. That will apparently extend to “songs that might be on an album that a listener owns just part of.” Interestingly, Apple also won’t pay for songs skipped before the 20 second mark and those included in special promotions, but it can only skip paying royalties on two songs per hour for each iTunes Radio user:

The deals are apparently not exactly the same for independent labels, and WSJ notes that Apple also makes references to not paying royalties for music used in “talk, weather, sports and news programming.” That could be a hint that Apple plans to bring that type of programming, and not just music, to iTunes Radio by the time it launches with iOS 7 in the fall.

There has been some controversy lately over the amount of royalties that Pandora pays artists through its free service, although reports of roughly $16 per million plays aren’t exactly true. Today’s report notes that “The ad revenue iTunes Radio generates might not necessarily be more significant than Pandora’s,” but Apple is hoping the higher royalty rates and increased iTunes song purchases coming from iTunes Radio will help make it the preferred service for labels and publishers.
