Foster City, Calif. - Sony extended its Music Unlimited streaming service to the portable PS Vita game player.
The company also announced a new capability that lets users cache streamed channels and playlists on the Vita and on select Sony Android smartphones for offline listening when a cellular or Wi-Fi connection isn't available.
Cached playback will also help users conserve battery life or manage cellular data-plan charges.
For Android smartphones, the cache capability is available on handsets running a new 1.3 version of the Sony Music Unlimited app operating on the Android 2.1, 2.2 or 2.3 OS.
Vita comes in Wi-Fi and Wi-Fi/3G versions.
Consumers who pay for a subscription to the personalized service are entitled to stream music to any PC and to any compatible connected Sony device, such as smartphones, tablets, and 2010 and later connected Sony Bravia HDTVs, Blu-ray Disc players, Blu-ray HTiBs, the Disc Home Theatre Systems, PlayStation 3, PlayStation Portable and PS Vita system.
For Sony Walkman MP3/video players lacking Wi-Fi, Music Unlimited turns into a subscription-download service in which music is downloaded to a PC and then side-loaded to the Walkman. Users can side-load individual songs or channels for playback on the portable devices.
