Google has made their Music service beta open to all U.S. users. It will allow users to upload roughly 20,000 songs into cloud storage and play them on any computer, including Apple, or on an Android smartphone running version 2.2 or better.

“The Google Music service will continue to be free,” Jamie Rosenberg, Google’s head of digital content for Android, said. “Other cloud music services think you have to pay to stream music you own – we don’t.”

There’s no charge for using the service, though data fees to apply for mobile. The service will make money by selling songs from Android market.
