The streaming music app isn't available yet, but, now that it's approved, it will launch in a few weeks. MOG will apparently cost music fans $9.99 per month for access to its entire music catalog.
(An Android version is also expected and the company has reached an arrangement with ROKU in which MOG joins Pandora as a service which can be accessed from a ROKU box, TechCrunch tells us.)
After years of speculation, some had hoped Apple would introduce its own music streaming service at WWDC earlier this month.
The company finally shuttered its recently-acquired Lala.com music streaming service on May 31, and had been expected to introduce a new streaming breed of iTunes along with the iPhone. This didn't happen.
Apple's delay in introducing MOG may have sparked speculation the company had its own streaming service plans.
The subsequent approaval of MOG could suggest Apple's own much-rumored plans for a music streaming service face obstacles.
If that's the case, then Apple isn't the only one facing such challenges. Spotify is king of streaming services in Europe, but hasn't yet launched in the US despite originally stating it intended to do so before the end of 2009.
Now expected to open up in the US in Q4, does the deal mean labels are reluctantly preparing to agree big streaming music deals in the world's biggest music market?
It makes a huge amount of sense for Apple to announce a Lala-based music service for its millions of registered iTunes users during its traditional Fall music event, when it customarily upgrades the iPod range.
That's when we can expect more details on iOS 4 for the iPad to get iOS 4 (some say November for this, though Apple CEO Steve Jobs promised this would come during 'fall').
It is also when we can expect the next model iPod touch to land, now equipped with a camera and (likely) other high-end features borrowed from the iPhone 4.
What better way to propel iPod touch sales than by introducing it as a device capable of accessing the widest possible streamed music catalog and the world's leading music store?
And that's even before the introduction of a WiFI-equipped iPod nano to accompany these releases, as Apple continues its series of significant moves to take its content empire into the cloud as the battle with Google continues.
Not to mention the Apple TV upgrade the company has been stealthily cooking up as it tries to create a fourth leg to its business, there's more to the television plan than the HDMI Mac mini, I suspect..
