Cast from Google Play Music to any UPNP/DLNA device
This might of interest to users of Google's Play Music.
Cast to UPNP/DLNA for GMusic (Bubblesoft) allows you to stream from Google Play Music to any UPNP/DLNA device (SmartTV, AV Receiver, BD Player etc), without any extra hardware.
Install and run the app. Then run Play Music and you will notice a new 'cast' icon. Just press it and select your target device.
(Previously you could only do this for local media, or by mirroring your entire phone to something like an HTC Media Link, or using an AirPlay/Bluetooth target).
