According to a new report form The Wallstreet Journal, Apple’s iCloud storage locker service — set to be unveiled next Monday during the WWDC 2011 conference — will launch with more partners than both Google and Amazon have for their competing services. Reportedly, Apple has inked deals with EMI Group, Sony Music Entertainment, and Warner Music Group. A fourth deal with Universal Music Group could be signed as early as this week, The Wall Street Journal said. In a more interesting twist, Apple’s music locker may not require users to upload songs, as Google and Amazon’s services do. Instead, it could “scan and match” user’s libraries and simply provide access to songs that have already been downloaded. What’s more, Apple may be working on separate deals with movie studios that would allow a similar service for streaming movies and TV shows. We’ll be reporting live from San Francisco on Monday, where Apple has also confirmed that it will discuss iOS 5 and its new OS X Lion operating systems.
