Did you know that music is good for your health.
Your brain releases dopamine when you listen to music that you love. So if you are a fan of Justin Bieber (I have no idea why though), listening to his music could be good for your mental state and making you feel happy. It's also why EDM has taken off in recent years, because a lot of people can dance and have a good time to to the music.
So remember kids, Justin Bieber can do good after all, but only as long as he is locked in a studio room to record songs.
