The early releases hit hard, while Better Day and Still Loving You near the end lean on singing; the group continued after losing leader Minwoo in 2018 and closed in 2021.
Come here for a third-generation boy group whose late material sounds nothing like its opening years.

Bad Boy MVBad Boy is the debut, and the hard-edged dance sound is the first image the group gave off.

KPOP DISCOVER's 100% note
100% is a K-pop boy group that debuted from TOP Media on September 21, 2012. The fandom is called PERFECTION. From the early dance songs to the later vocal direction they hold a catalogue of some nine years, and group activity closed in 2021 when the contract with TOP Media ended. Through the run they released in Korea and Japan in parallel, delivering How to Cry and Warrior in Japan. In 2018 they came through the news of the leader Minwoo's death, and the remaining members carried on.
The three songs to hear first are Want U Back, Bang the Bush and Better Day. Want U Back is the signature song from the year after the debut, and sharp choreography and a hard-edged expression cut the early image of 100% exactly as it was. Bang the Bush, from 2014, is dramatic in tone and takes both the pressure of the voices and the intensity of the performing. Better Day stands for the vocal direction established from 2016, where the weight of the singing comes right to the front. To fill in the poppier colour, Sunkiss alongside them brings the summer 100% into view.
The turning point is around Time Leap, released in 2016, when the group moved its centre of gravity from dancing to songs carried by singing. In the end they built the catalogue as the four of Rockhyun, Jonghwan, Chanyong and Hyukjin, and Still Loving You in 2019 left a matured expression. Want U Back, then Better Day, then Still Loving You covers the early dancing, the established vocal direction and the maturity of the later period.
Editors' take Want U Back / Better Day / Still Loving You — three songs cover the path from dancing to singing, in a TOP Media four-piece.
Trivia worth knowing
The name 100% points to giving everything on stage, and the fandom name PERFECTION answers it.
100% V put Rockhyun, Jonghwan, Hyukjin and Chanyong together as a four-piece and concentrated the singing and the rap.
How to Cry, Warrior and Summer Night belong to a wide run of Japanese releases.
Better Day, Sketch U and Still Loving You introduce 100% as a vocal group.
Seven members at the start, four at the end, and the death of Minwoo in between: keeping those apart makes the timeline legible.
Rockhyun, Jonghwan, Chanyong and Hyukjin restarted as FAVE1, which is where the story of 100% carries on.

The denominator is the 241 groups, out of 564 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
