KPOP DISCOVER's IMFACT note

What runs through IMFACT is the change from a bright start to a polished later stretch. Star Empire Entertainment debuted the five-member boy group in January 2016 with Lollipop, and the roles of rap, main vocal, production and performance sit clearly apart from one another.

Lollipop, Feel So Good and Nanana form the way in. Take the bright debut song, then the early track with momentum, then the polished sound of the later years in order, and the change IMFACT went through falls into place.

There is the singing of Jeup and Taeho, the production work of Ungjae and the leader and rap line of Jian, so The Unit and the solo careers can be read as routes back to the group. What remains is not only a short run of activity but the individual strengths of the members. Lollipop, then Feel So Good, then Nanana carries the brightness, the momentum and the polish.

Editors' take Lollipop / Feel So Good / Nanana — a Star Empire five-piece whose path from a bright start to a polished finish fits into three songs.

Japan activity score

KPOP DISCOVER original metric
No. 178/ 210 groups

No. 178 of 210 groups with recorded activity in Japan (top 85%)

  • 1Japanese releases
  • 2Japan-related tracks
  • 0Members from Japan
  • 0Official Japanese accounts

The denominator is the 210 groups, out of 525 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.
