The aim of the show is to highlight the talents of the vocalists of twelve lesser-known girl groups that debuted in recent years.

In addition to the gurus, the contestants' performances will also be judged by 100 "listeners" – men and women who are studying music and have dreams of becoming singers themselves – for a total of 105 maximum points.

During the first round, each of the gurus, listeners, and opposite team members will have a device which they will use to cast their vote for the contestants whose performances they liked.

The contestant who comes in first place then chooses the order in which the members of that team will perform on their next episode.

As an "unstated rule," contestants may perform a "pop song" (English language song), as well as have a "wild card" (featured artist) in a performance only once throughout the competition.
