auto start/run google play music

[joszeph]

I want google play music to start playing music when i choose bluetooth on my cars radio.

In the past this worked fine. Google play music kept running all the time. Now it disappears after a random time. When i choose bluetooth on my car radio, it then starts the default samsung app, which only has one default music song.

How do i get google play music to start automatically or to keep running all the time?

My buddy used to have this -- only way was with root and using Tasker.
