Earworm's Curse

You hum or sing a song softly under your breath laced with a subtle enchantment. Every creature of your choosing within a 30 foot radius must make a Wisdom Saving throw. If failed the tune of the song enters into mind and refuses to leave, thoroughly distracting them for the next 10 minutes. They are at a disadvantage to all insight, investigation, perception checks, and have disadvantage on rolls to maintain concentration spells for the duration. If they roll a 1 at anytime during these checks, then the duration resets and they use their next action to loudly repeat the piece of melody that they cannot forget. A deafened creature automatically succeeds on the save.

You can recognize when their spell is affecting an individual, and can use an action to end the effects on one target, or take 1 minute to end he spell entirely. A remove curse spell or a bard's countercharm ability will also end the effect.

At Higher Levels. If you cast this spell using a spell slot of 3rd level or higher, the duration extends up to 1 hour. If you use a spell slot of 4th level or higher, the duration is 8 hours. If you use a spell slot of 5th level or higher, the duration is 24 hours. If you use a 7th level spell slot, the spell lasts for 1 week. Using a spell slot of 5th level or higher creates an additional effect where when an affected creature repeats the melody of the spell due to rolling a 1 on an affected check, all creatures within 30 feet of that affected creature must make a wisdom save, also suffering all the effects of the originally cast spell on a failed save.
