According to Soompi, the official dance practice video for ITZY‘s song THAT’S A NO NO (Korean title: 그건 노노) reached No. 1 on YouTube’s trending chart in South Korea. The placement is based on YouTube’s official trending rankings in the country and was reported in an article published March 15, 2026.

This milestone underscores how central dance practice videos have become to K-pop fandom and promotion. For ITZY, who are widely recognized within the Korean entertainment industry as a leading girl group, releasing a high-quality, official practice clip is a familiar way to highlight choreography, showcase members’ performance skills, and provide shareable content that engages both domestic and international audiences.

What makes such practice videos notable is their combination of polished production and raw performance focus: viewers can watch choreography executed in full, often filmed in simple rehearsal spaces that emphasize movement and synchronization. Available reports indicate that K-pop idol groups’ dance practice content continues to attract strong interest, and ITZY‘s recent upload evidently resonated enough with viewers in South Korea to top YouTube’s local trending list.

The connection between music program promotions and supplementary video content also helps explain the wide fan response. When a high-profile group posts a performance-centered clip around the time of broadcast promotions, the overlap in attention—between people tuning into televised stages and those seeking repeatable, study-friendly practice footage—amplifies reach and interaction across platforms.

For fans who want to find the clip, a simple search using the phrase “ITZY THAT’S A NO NO 댄스 연습” is likely to surface the official practice video and related coverage. As Soompi’s report highlights, the trending position reflects current viewership patterns on YouTube in South Korea and serves as a snapshot of which K-pop releases are capturing public attention at the moment.
