🎵 Can't get a song out of your head? 🎵

An earworm, a term derived from the German “ohrwurm,” is defined as a “cognitive itch” or “the inability to dislodge a song and prevent it from repeating itself in one's head”. This phenomenon has recently become a burgeoning area of neurological study.
These worms are the result of our memory's tendency to remember incomplete tasks better than complete ones, a phenomenon known as the Zeigarnik effect. Sometimes you don't recognize the song and sometimes you don't remember the lyrics.
