On my iPod I have activator to automatically open Spotify when I plug in my headphones and I would like to know if I can do a similar thing on OS X.
What I would like is to automatically play Spotify if the application is already open, otherwise, I would like Spotify to open automatically then play the music. I would also like it to stop the music when my headphones are unplugged.
Does anyone know if there is a Application that allows this to happen?
