Google's Play Music app now supports an extended range of Google TV devices and expandable notifications in Jellybean thanks to a new update. Up until now, newer Google TV boxes like the Sony NSZ-GS7 and Vizio Co-Star were incompatible with the app, but, according to Android Central, this update takes care of that.
One of many new features to arrive with Android 4.1 Jellybean was improved notifications that allow for rich interaction with apps without ever leaving the notification tray. In the latest Google Play Music, version 4.3.609, you're now able to view album art along with standard music controls as a persistent notification. Android Central is also reporting that early adopters of the Nexus Q media streamer will gain a quick link to the media streaming device settings after updating. The update is available from the Google Play store as a free download.
