I made a tasker app to solve this.
I made it how I want it to work anyway.
Install the app. It will be called "Shuffle".
Do your ok Google now or whatever you say to open touchless control.
Say "open shuffle"
The app will be opened. It opens Google music, starts playing music on shuffle mode. Then goes back to your home screen. Then I use Bluetooth to control it...like next track and whatever. Or you can drag down the status bar and control it that way.
Works great for me! Thought I'd share it with those interested.
Of course you don't need tasker, cause it's an app now. But you do need root and have to grant it root permission. Don't know why....tasker just makes it that way it seems.
Enjoy.
