This video ranks idol group songs that were released in the same year by their total unique listeners on Melon. If there is a tie, the song with more streams is ranked higher. The only exceptions are Brave Girls' Rollin, We Ride, and LABOUM's Journey to Atlantis. They are considered 2021 songs due to going extremely viral that year.

For 2023, the peak unique listeners in 24 hours were used for the ranking. It's still 2023 so using the peak ULs makes more sense than total ULs. Only 6 songs were ranked instead of 15, to represent that only 40% of the year has passed.
