In 30 seconds: TO1
The early releases go dark and heavy with a large cast in tight synchronisation; the 2022 material plays with rhythm and lets the expressions open up.
Pick this if you want several choreography versions of every title track and a clear before-and-after in one catalogue.

KPOP DISCOVER's TO1 note
TO1 comes into focus when the changes of name and line-up are not viewed apart from each other. Going from Magnolia and Count 1, 2 of the TOO years to Son of Beast and No More X as TO1 shows a process of raising the density of the group choreography while moving between light and dark.
Drummin' and Freeze Tag from 2022 come not only with a standard Dance Practice but with Choreography and Special versions as well. Even after the line-up changed, adding formats and widening how a single song could be played with is what makes following the official channel of this group worthwhile.
Editors' take Across a renaming and a reshuffle, this group left the shifts in its formations inside alternate versions of the same dance footage.

Japan activity score
KPOP DISCOVER original metric
No. 169/ 241 groups
No. 169 of 241 groups with recorded activity in Japan (top 70%)
- 0Japanese releases
- 0Japan-related tracks
- 2Members from Japan
- 0Official Japanese accounts
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.
