WD TV Live Hub Music Play App

I could see many combinations for music play like “speaker + media center + app” in the market these days. I believe this is a trend especially for music. People may see the music list on the phone and just touch it to play. I thought this is supported by WD TV Live Hub, but it seems not. I have “Live Hub - Receiver - Speaker - TV”. I may not need to turn on TV if it is supported. 

I saw another post which someone asked to play to any DLNA device. I found an app to support it which is “WD TV Live Media Player by Zappo TV”. But this was very bad… slow and bad UI.

We may not need to play to another DLNA device. It would be great if we can just play on Live Hub from an app. I believe many people is waiting the kind of app.
