Will Google's Music Beta change the music industry? That remains to be seen, but having room for 20,000 tracks in the cloud is certainly interesting. And free? Yeah, free. For now, but still, it's free. Google is now sending out Beta invites to the general public, just a week after giving them out to Google I/O attendees and a day after providing them to Motorola Xoom owners.

The question is simple: are you signing up? Or are you waiting for something better to come along? And would you switch to Android for this?
