APPLE'S iCLOUD MUSIC SERVICE WILL MIRROR YOUR iTUNES LIBRARY

There's been so much chatter about Apple iCloud that you'd think the streaming music service had already been announced and the deals inked. But it's still just a rumor until an Apple executive takes the stage and unleashes the Amazon Cloud Player and Google Music competitor in a spate of superlatives. That hasn't stopped Businessweekfrom stepping up with a good summary of all that is "known" thus far, while giving us some insight into the particulars of how the service will work and the motivations to make it happen. One revelation, sourced from three people in the know, claims that Apple will scan customers' iTunes libraries (hello, LaLa) and quickly mirror the contents on Apple's own servers -- no massive DSL-choking upload required. And Apple will do you the solid of "replacing" any low bitrate tracks with the "high-quality" versions it stores in its fully licensed music locker for streaming to your connected devices.

GOOGLE MAKES GOOGLE MUSIC OFFICIAL

Called "Music Beta by Google" at this point, it's a simple presentation with artists, albums, and easy playlist creation. You can manually create them, or there's a feature called "Instant Mix" that will make you a playlist based on any single song. It'll automagically pick 25 different tracks to build a "truly ingenious mix." You know, kind of like another, similarly intelligent service. All of this syncs to the cloud, which means no wires needed to download anything.

But, more importantly, songs can be cached locally. You can pick any song, album, or playlist to download onto storage, at an unknown quality. It's the same pinning idea that's in the new movies feature. That and more is demonstrated in the video below.

The service is launching in beta today, allowing 20,000 songs, and it'll be free -- "at least while it's in beta." Also, the updated music app is available now, which will work with any music on your phone and any phone running Android 2.2 or above.
