In 30 seconds: Playback

Woolim, Yunji, Yujin and Hayoung debuted as four, Eunjin joined later, and the label's connection to Jessica's work sometimes brings people here sideways.

Worth a look if you like small catalogues where the singing carries everything.

From debut to now

  • 2015
    Woolim, Yunji, Yujin and Hayoung debuted as a four-piece and, in the same year, released I Wonder with Eric Nam, leaving a bright R&B pop and vocal-leaning entrance.
  • 2016
    Without new releases, official stage footage from Arirang and elsewhere still shows the voices, the expressions and the formations of the debut period.
  • 2017
    Eunjin joined, and Want You To Say arrived with five members. The 1theK music video and the official Coridel Performance Ver. became the representative routes.
  • 2018
    Television routes around Hayoung and Woolim left a way back to Playback itself, a group with little activity to show.
  • 2020
    Hayoung's departure was confirmed, and from then on the group is traced mainly through its releases and official footage as a short-lived act.

KPOP DISCOVER's Playback note

Playback debuted from Coridel Entertainment in June 2015 as a girl group. They set out as a four-piece of Woolim, Yunji, Yujin and Hayoung, and Eunjin joined in 2017 to make five. The team colour built on R&B pop held steady from the debut onward, and they are sometimes discussed alongside the label context around Jessica. Hayoung's departure was confirmed in 2020, and since then the group is traced through releases and official footage rather than current activity.

Start with two songs: Playback and Want You To Say. The debut song Playback shows the individual character of four voices and the feel of bright dance pop. I Wonder, released the same year, features Eric Nam and leans on singing, which makes the raw vocal strength easy to hear. Want You To Say, from 2017, is the first major work after Eunjin joined, and both the formation of five and the depth of the R&B pop go up a step.

The active span from debut to around 2020 is only a few years, and the release count is not large. That is exactly why each piece of footage is dense: the singing of Woolim, Hayoung on MIXNINE, Eunjin's Produce 101 and Kpop Star history, so several doors back to individual members remain. Letting the small number of works act as the guide, Playback, then I Wonder, then Want You To Say covers the early dance pop, the raw vocal strength and the depth of the five-member lineup.

Editors' take Playback / I Wonder / Want You To Say — vocal-led R&B pop in three songs, out of a Coridel Entertainment five-piece.
