“Commas” was posted to JYP Entertainment’s own YouTube channel under the name GIRLSET. The description attached to it is a single copyright line, which is ordinary practice for a major Korean agency.

Korean pop counts itself in generations

Read any English-language coverage of Korean music and you will hit phrases like “third-generation group” or “fifth gen”. It is not an official classification; no ministry or trade body issues it. Fans and journalists use it as shorthand for a cohort that debuted in roughly the same period and worked under roughly the same conditions — the first generation in the late 1990s, when H.O.T. and S.E.S. set the template, a second wave from the mid-2000s, and onward at intervals of about five years. The boundaries are argued over endlessly, because nothing fixes them but consensus.

About this release

The video is credited to JYP Entertainment, which is both the rights holder and the owner of the channel it appeared on. No album, single or EP title accompanies the video title, and the description carries only the 2025 copyright notice, so no producer, writer or guest performer is named there. It was published on 3 September 2025, Korean time.

Watching from outside Korea

Korean releases are usually timed to the evening in Seoul, nine hours ahead of UTC, so they surface mid-morning in Britain. Any subtitles sit under YouTube’s CC button rather than in the description, and agency channels often add further languages days after the upload.
