just a small idea but I think that they should make headphones to where when you first put them in, no sound comes out and you are required to smile to turn up the volume so you can hear. Even when you are deeply depressed, or angry, or just sad, even a fake smile sends off “happy hormones”. Not only will that happen, and you’ll feel a little better, but you’ll get to listen to music too, it’s a win-win.
