Success!!!
If you have access to a windows PC, download and install the Play-fi App and install it. Open www.radiogroove.hu/live.mp3 in a browser and make sure it is playing. Open the Play-FI app on your Windows PC and make sure it's in music mode, then select the Play-Fi zone you wish to play it in. The Windows PC becomes the Renderer and transfers the audio stream to the Play-Fi device. The only downside to this is that the Windows PC has to be on whenever you wish to listen. I tried adding it to a preset button on one of my Play-Fi speakers, but it didn't take.
