Default Is there a way to change the default music player?

Hi everyone,
Is there a way I can disable the Samsung Music Player from being the default player, and switch it to Google Music?

Currently, when I plug my headphones in and press play, it auto starts Samsung Music. - I don't want that.

Any ideas?
