The program is a weekly music show that features and introduces viewers to the most popular artists in Korea. Every week, they ask viewers to vote and select the most popular song of the week.

Idols who failed to impress the audience after their debut are given another chance to be back on stage in The Unit. Korean top producers will give them a chance to shine in a brand new unit with new members, concepts and content. (Contestants credited here are sorted by final rankings.)
