Google has released all kinds of new goodies today at their I/O keynote today in San Francisco, this time Google has announced a new music streaming service called Music by Google. It's currently in beta and on invitation only basis. The whole point of Music by Google is to let you upload your music collection to Google's cloud storage and then you will be able to stream and listen to your music online and on your Android device using the Android Music app, for free. Songs that you've already fully played will be cached on your device and will be available for offline listening. Possibly the best thing off all is the ease of use, users will be able to directly upload their music library straight from iTunes or any music folder. What are you waiting for? Go request a Music by Google invite, it's free!
