Playing Music from Media Server Via ST

Has anyone found a way of having a Smartapp that can read the catalog of songs from a Media Server/DLNA server and then playing it to your Networked Speakers?

I have 2 Samsung Shape M5 speakers that are connected to my ST setup. I have an 8TB NAS that runs a multitude of services including, DLNA server, Twonky Server, iTunes Server and so on.

Is there anyway of getting ST to recognize this and allow tracks to be displayed in the “play this track” function?

Currently all I have is the pre-installed voices
