Earworm

Choose one creature that you can see within range. That creature must make a wisdom saving throw or be charmed for the duration. The target becomes distracted and begins singing/humming/whistling the tune for the duration. Creatures that cannot hear are immune to this spell, as are creatures immune to charm effects.

A singing creature must use its action to sing the song you’ve placed in its head and has disadvantage on Charisma saving throws. While the target is affected by this spell, other creatures have advantage on attack rolls against it. At the end of its turn, a singing creature makes a Wisdom saving throw. A successful save will end the spell and charmed effect.
