ITZY’s “THAT’S A NO NO” Is Finally Getting Its First-Ever Music Show Performance — 6 Years Later!

Sometimes a song just needs its moment — and for ITZY’s “THAT’S A NO NO,” that moment is right now. Six years after quietly sitting as a B-side, this track has exploded into a viral phenomenon, and fans are absolutely losing it. Here’s everything you need to know.

ITZY Song That Time (Almost) Forgot

“THAT’S A NO NO” was originally a B-side on ITZY’s 2020 mini album IT’z ME — a deep cut most casual listeners had never heard. That all changed when ITZY launched their 2026 TUNNEL VISION World Tour in Seoul, debuting brand-new choreography for the song live on stage for the very first time.

The crowd went wild. Clips flooded social media. The song shot up the charts at remarkable speed — proving once again that great music always finds its audience, even if it takes half a decade.

Why This Performance Is Such a Big Deal

This will mark the very first time ITZY performs “THAT’S A NO NO” on a music show — something MIDZYs (ITZY’s fanbase) never thought they’d see. The performance on M Countdown on March 19 is set to be one of the most talked-about K-pop stages of 2026.

What makes this extra special is the organic nature of the song’s revival. No repackage, no official push — just a live performance that clicked with audiences and spread like wildfire online. That kind of genuine fan momentum is rare and beautiful in today’s highly manufactured pop landscape.

For fans who’ve been following ITZY’s journey since their debut, this feels like a full-circle moment. If you want to catch up on ITZY’s rise and the biggest K-pop moments of 2026, check out our latest K-pop coverage on TechnoSports for everything you need.
