  • 2021

KPOP DISCOVER's Rocket Punch note

What holds Rocket Punch together is a clean, breezy tone and a gradual turn toward retro pop. Woollim Entertainment launched the six-piece girl group in August 2019, and the name fits the music: brisk songs and open expressions on stage are the way in.

The catalogue splits cleanly by mood. There is the cool rush of the debut BIM BAM BUM, the hard beat of BOUNCY, the summer heat of JUICY, the retro synth pop of Ring Ring. Japanese work such as Bubble Up! sits in there too, so the K-pop and J-pop threads can be followed together.

In May 2024 Juri left at the end of her contract, and later that year the contracts of several more members ended, closing a run that had opened in 2019. Playing BIM BAM BUM, then BOUNCY, then Ring Ring traces the move from cool brightness through a harder beat to retro pop.

Editors' take BIM BAM BUM / BOUNCY / Ring Ring — three songs tracing the shift from cool brightness to retro synth pop, from Woollim's six-piece girl group.

Japan activity score

KPOP DISCOVER original metric
No. 73/ 210 groups

No. 73 of 210 groups with recorded activity in Japan (top 35%)

  • 4Japanese releases
  • 5Japan-related tracks
  • 1Members from Japan
  • 2Official 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.
