As we reported yesterday, Google unveiled Music Beta, a new service that will allow users to upload music on the cloud and stream in on any device using web browser or your Android device.
Currently via Invitation only, Music is free for beta testing and users can upload upto 20,000 songs. Music beta helps you keep you music and playlists in sync. There is another feature called Instant Mix, which helps you create playlists of songs that go well together, so no long hours creating playlist manually.
To your respite, you can also listen to this music offline, as Google Music beta stores the recently played music cached on your Android device, as well as you can mark few other albums which you want to be available without data access.
