The TV is wired to the network and sees any uPnP/DLNA players on my network like Plex, or in this case Foobar2000 Media server. I use Foobar2000 controller on my phone connected to WiFi on the same network, but I don't have it set up to access from outside...though you could.
I got all of the info here
and here

Gotta pay a few bucks for it but it works great. Album art, playlists, library, whole 9. I can leave my TV off my HTPC and just listen to tunes using this as the remote.
