I have spotify premium, but I can't figure out how to get it playing from my PC through my Sony stereo system which is DNLA enabled. It is a Sony CMT-MX700Ni. Can you only play spotify through its partner products?
Hi. Spotify doesn't support streaming via DLNA right now but you might want to add your support to this idea. It is possible to set up a DLNA server on your PC using software such as Jamcast or PS3 Media Server and you'll find plenty of guides on how to do this with a Google search.
