Earworm

A bard plays a short snippet of a song. The target must make a CON save. On a successful hit, the target has the song stuck in their head for 10 hours, or until one long rest, and is minorly distracted. Any roll the target makes, 2 points are taken off of it until the end of the enchantment. To remove the enchantment, the target must roll to intimidate the caster, at disadvantage with the -2, to finish the song, and the caster must make a CHA saving throw. If the target's intimidation roll is bad and the caster succeeds the save, another 10 hours is added to the previous duration.
