For few month's i am using Google music
, and I really love it but it has one disadvantage until now, I didn't know how to configure global shortcuts. Finally i found how to do that
Firstly install Google mini player by clicking button in player
It will install chrome extention.
Then go to Options -> More tools -> Extensions Scroll down on page and on the right bottom of the page there is link Keyboard shortcuts click on that link to open popup for configuration. Mine look like following example
Now if you work you can use them to control your music :)
