[Problem] [CM11] [App] Disable autostart Google Play Music when plugin headset topic

Hello!

I have 2 music players installed on my SGS2: GoneMAD Music Player and Google Play Music.

When I plugin headset to the device, Google Play Music is starting up automatically.
I don't want this.
Actually Google Play Music is over-ruling the setting in GoneMAD Music Player.

Question:
How do I disable autostart of Google Play Music?
