AtHeart released the official music video for “Shut Up” on their own YouTube channel in February 2026. The group is a recent addition to the Korean girl group field, working under TITAN CONTENT.

Video keywords are a searchable member list

Every YouTube upload carries hidden keyword tags that the uploader sets and viewers never see on the page. Korean agencies use them methodically, and one common practice is to list each member’s stage name individually alongside the group name. The reasoning is practical: a newcomer who only knows one member by face or name should still land on the group’s official video rather than a fan re-upload. For AtHeart, those tags name MICHI, SEOHYEON, AURORA, KATELYN, BOME, ARIN and NAHYUN. Third-party tools can surface these tags, which is why fan wikis sometimes cite a member roster before any formal profile is published.

About this release

“Shut Up” is the title of the release the video accompanies, published on the AtHeart channel in February 2026 with the copyright line attributed to AtHeart. The official description is minimal — the title, the hashtags #ATHEART, #앳하트 and #shutup, and a link to the group’s social accounts. No producer, featured artist or full tracklist is listed there.
