Sony joins EMI and Warner in Apple cloud music service

Three down, one to go. Just a day after CNET suggested that EMI joined Warner Music Group in allowing Apple to distribute their music over a cloud-based service, now Bloomberg is claiming that Apple has also officially inked a deal with Sony Music. That leaves just one of the big four music labels -- Universal Music Group -- left to sign on with Apple. And as Bloomberg states, Universal is supposedly close to signing with the iPod maker soon.

As I mentioned yesterday, getting all four major music labels to sign on to a cloud-based service is seen as a serious win and another vote of confidence for Apple's rumored streaming media services. Both Google and Amazon launched their online music services without any major music label support. Apple's cloud music service, expected to be dubbed iCloud, may be unveiled at WWDC on June 6.
