Subscription music service MOG has released a desktop client for Mac OSX and promise a Windows client soon.  MOG had previously been available only as a web service and via mobile apps. Many Spotify users appreciate the speed and stability of its desktop based system, and MOG is smart to compete on all fronts.  Features of the MOG's new MAC desktop client include:

• Built-in AirPlay support: Stream directly to your stereo system via Airport Express, AppleTV, and all other Airplay-enabled devices.
• Native audio decoder + 320 kbps - higher fidelity audio than our HQ web player.
• Keyboard shortcuts : Use Apple's media keys to play/pause/skip backward & forward through the play queue.
• Remote control: Use Apple remotes to control playback at a distance.
