Stray Kids '그날 (Back Then)' Video

What happened

This is JYP Entertainment's "SONG by" series entry for Stray Kids' "THIS & THAT" era — a standalone vocal-focused video giving member Seungmin (marked by the #승민 #Seungmin tags) his own rendition of the track "그날 (Back Then)," separate from the group's main comeback promotion.

Why Koreans care

"SONG by" (also tagged #송바이, the Korean transliteration of the same name) is a recurring JYP content format that gives one member of a group a standalone performance clip built around a single non-lead track per comeback — distinct from a "moving version" or self-filmed content. It exists specifically because group comeback promotion tends to center on the title track and its featured vocalists/rappers, so this format is a label-driven way to still spotlight another member individually. For Stray Kids, whose songs are largely written and produced in-house by the 3RACHA unit (Bang Chan, Changbin, Han), giving a "SONG by" clip to Seungmin — who isn't part of that writing unit — is a way to hand him a personal spotlight moment tied to the release.

What the words mean

A foreign viewer could assume this is the era's main music video; "SONG by" clips showcase one member on one song from the album and are not the lead single driving the comeback's promotion. Separately, the title "그날" literally just means "that day" — not a named or specific date, but a deliberately vague placeholder that Korean ballad/love-song lyrics commonly use so listeners project their own memory onto it; "Back Then" is a loose English rendering of that vagueness, not a literal word-for-word translation.
