Coming as a nice follow up to the Google Music Beta announcement, there is now an updated version of the Google Music app available in the Android Market. The latest update brings the Google Music app up to version 3.0 and it comes as a 3.8MB download and remains available for free. Of course, the big (and only) addition in this update is the now included support for Music Beta by Google. Otherwise, the Music Beta service is available only by invitation, however once you get your invite you will be able to upload and store 20,000 tracks for free.
