Apple signed Universal Music last month and Warner followed just this past weekend, but Sony and Apple were reported to be having difficulty reaching an agreement over compensation for songs skipped by users.Sony Music has signed on to Apple's forthcoming iRadio service, according to a person familiar with negotiations between the two companies.
The deal means Apple now has agreements with all three major music labels.
Still to be negotiated are deals with publishers, but those talks are said to be less contentious than those with the labels.
Apple's iRadio service will reportedly be free to users, with revenue generated through advertising managed by Apple's iAd program. The service would most likely launch alongside iOS 7 later this year.
