Google today announced the preliminary launch of its new cloud-based music service. Dubbed Music Beta by Google, the service allows users to upload up to 20,000 songs—including iTunes libraries and playlists—for playback across devices. Features include an automatic playlist creation tool, similar in concept to Apple’s Genius feature, automatic wireless syncing, and the ability to “pin” music for offline access. The service is currently available by invitation only and will be free while in beta; formal pricing has yet to announced. In addition to the Music Beta service, Google today also announced movie rentals from the Android Market, an Android Open Accessory initiative for creating third-party accessories, and the Android @ Home protocol that will allow Android devices to communicate with other products, such as lighting, audio, appliances, and heating/cooling systems, using low-voltage technology.
