Senior three, what should I do if I always play songs in my head when I study? It's been there for three days.

Try to ignore it, give yourself psychological hints, constantly hint that music is not important, and tell yourself that it doesn't matter if you hear it. You can even follow the melody for a while, then pull it back in time and come back. Use the alarm clock or ask your classmates for help, do exercises at a fixed time, concentrate, stop listening to any music after study, exercise, relax your mind and strengthen the control of time, and this strange music will come out. I was like you in my senior year. My classmates and I have used this method, so we can try it.
