ITZY will bring their viral hit "THAT'S A NO NO" to the music show stage for the first time when they perform on the March 19 episode of "M Countdown."

The track, originally a B-side from their 2020 mini album, has gained massive popularity over the years despite never receiving an official music show performance. Six years after its release, the song has become a fan favorite and social media sensation, making this upcoming performance particularly meaningful for both the group and their fans.

"THAT'S A NO NO" showcases ITZY's signature confident energy and catchy hooks that have become their trademark sound. The song's delayed recognition mirrors how some B-side tracks can find new life through fan appreciation and viral moments, sometimes even surpassing title tracks in popularity.

The decision to finally perform the track on "M Countdown" acknowledges the song's organic growth and enduring appeal within the ITZY discography. For many fans, this will be the first opportunity to see the group perform the beloved track in a formal music show setting.

ITZY debuted in 2019 and quickly established themselves as one of fourth-generation K-pop's standout acts. Their discography includes numerous hits like "DALLA DALLA," "ICY," and "WANNABE," but "THAT'S A NO NO" represents how deep cuts can sometimes resonate just as powerfully with audiences.

The March 19 "M Countdown" episode will mark a special moment for longtime fans who have been requesting a live performance of the track. The performance comes as ITZY continues to evolve their sound while maintaining the bold, self-assured image that first captured fans' attention.

This long-awaited performance demonstrates how K-pop groups can revisit their catalogs to celebrate tracks that have gained significance over time, giving both artists and fans a chance to experience beloved songs in new ways.
