Play key opening iTunes even if Spotify is currently selected I normally use spotify for music, but I go from time to time to iTunes to listen to some Podcasts.

Sometimes I have both applications opened, and when I want to stop one, I select the application and (⌘ + tab until finding the app) and I hit space which stops playing it.

The thing is that I developed that habit because of the play/pause key wasn't working, and was only stopping iTunes if it was opened.

I would like the play/pause key (and all music related keys) to work on the app that I selected last, is that possible or configurable?

I am using a Macbook Pro with Touch Bar (Mojave 10.14.1)
I found this for you.


  Mac Media Key Forwarder
  
  Forwards media keys to iTunes or Spotify directly.
  
  You can prioritize which app you would like to control or you can go
  with the default behavior which controls the running app. The app
  runs in the menu bar.


It has some limitations.

It might not work on Mojave till (if) the developer fixes it.
