Play_media service with google play music

Configuration
1

So I’ve using my holiday as best as I can, trying to automate as much as I can around the house. I finally got off my lazy butt and integrated my google home with home-assisstant. I can run scenes just fine. My wife asked the google home to play some of her music and I saw it come across in the logs which got me thinking, could I have it play my playlists. So I looked and saw multiple URLS formatted like the below. SLT & SIG were changed everytime I would ask it to play the same playlist. Anybody successfully called a play_media service with google play music

I have been pulling my hair over this aswell. If someone knows how to do this that would be extremly helpful.

I have made a custom component to play playlists from google music: Google music in HA
It is not easy to setup, and might only work with chromecast.
