 Get rid of the song stuck in your head. People with certain personality traits are especially susceptible to earworms, which makes sense because the more stressed out, the more vulnerable you are. I know why the song was in my head. Having too much on your mind pushes your brain to latch onto a repetitive melody to distract you from whatever it is that's stressing you out in the first place. And before you know it, baby shark is in your head. Don't block it out and just accept it. Your brain will play it on loop over and over again if you resist. Earworms happen when you remember only a part of the song. Hearing the whole thing is your best bet to clear it out. And remember, it's not just you. 98% of people have experienced an earworm. They're so common there's a scientific name for it. Stuck Song Syndrome.
