So I've been searching for a decent way to play music while gamestreaming on my SHIELD. The best way I've found is by playing the music on Google Play music, then launching the stream through Moonlight (gamestream stops the music when it launches). My only problem with this setup is that the volume is much higher on the music than the game and there's no way to change this. The app even dampens the sound of the game when a track is playing, and in between tracks the game blares.

Has anyone found a better way? Is there perhaps a way to get music on my PC playing through the stream? I've tried with Spotify but it doesn't pick up the audio on Gamestream at all.

Essentially what makes me wanna do this is the lack of soundtrack on the new Mad Max game, so I want to play with the Fury Road soundtrack in the background, but not blaring over the game like it currently is.

Any suggestions?
