Last May at Google I/O, we launched Music Beta by Google with a clear ambition: to help people access their music collections easily from any device. Music Beta enabled you to upload your personal music collection (up to 20,000 songs) for free to the cloud so you could stream it anywhere, any time. Today, the beta service evolves into a broader platform: Google Music. Google Music is about discovering, purchasing, sharing and enjoying digital music in new, innovative and personalized ways.
