If you are trying to save time and clicks, you can set your music player to automatically play when you plug headphones in. That's how mine is set up. I use poweramp, which is by far my favorite music player (it sounds amazing and is really great for customization), and I have it set to autoplay when I plug my headphones in. I disabled the stupid "Audio Applications" thing in the notification bar because it just got in the way of my other notifications. Poweramp's player controls show up in the notification bar when it is playing music, so if you need to plug headphones in but don't want music, you can pull your notification bar down and turn it off as it comes on. 99% of the time I'm playing music when I put headphones in, so this was the ideal solution for me.
