Online music service MOG has released an update to its music player for the iPhone and iPod touch, adding iOS 4 background audio support and several other new features. MOG is a subscription-based service that allows users to listen to personalized radio and music on demand via a web browser on their computer or a mobile app on iOS devices. The mobile application for the iPhone and iPod touch provides access to CD-quality music streamed on demand or downloaded directly to the device for offline listening, automatically syncing with settings and playlists on the MOG web site. Users can create personalized listening experiences by using music discovery modes or choosing from a selection of featured playlists. MOG 1.2 now provides background audio support on multitasking-capable iOS 4 devices allowing users to continue listening to their MOG playlists while using other applications as well as taking advantage of lock screen playback controls. The latest update also includes support for audio remote controls, in-line headphone remotes and third-party hi-fi docks and includes larger album artwork in downloaded tracks. MOG 1.2 is available from the U.S. App Store as a free download; a three-day free trial of the MOG online music service is available after which a $10 monthly subscription is required to continue using the app.
