NSYNC's Viral Dance Is Back, and BTS Just Made It Bigger

A dance from 1997 is suddenly everywhere again. NSYNC's music video choreography for "I Want You Back" is going viral all over the internet, nearly three decades after it first came out. And a huge part of why it's blowing up right now comes down to two members of BTS.

Why This Old Dance Is Trending Again

"I Want You Back" was NSYNC's very first single, and the choreography that came with it, sharp, synchronized group moves, became one of the most recognizable dances of its era. Decades later, that same routine is showing up all over TikTok and other short-form video apps, with people learning it, recreating it, and putting their own spin on it.

BTS Gave It a Massive Boost

The trend hit a whole new level when BTS members Jungkook and J-Hope posted a TikTok video of themselves dancing to "I Want You Back" to help promote their upcoming Europe tour. With two of the biggest names in K-pop putting their own stamp on a 90s American boy band dance, the clip spread fast, pulling in fans from both fandoms and plenty of people who just found it while scrolling. It's a perfect example of how one video from the right people can send an old trend soaring all over again.

Who was NSYNC

NSYNC was a five-member American boy band that formed in the mid-90s and became one of the biggest pop acts of that era, known for tight harmonies and even tighter choreography. One of those five members was Justin Timberlake, who used the group as his launching pad. After NSYNC, he went on to become a massive solo star in his own right, and that early training in performing and dancing with the group helped shape the career he built afterward.

Part of a Bigger Y2K Wave

This isn't happening in isolation. Right now, there's a much bigger wave of Y2K nostalgia rolling through fashion, music, and internet culture, with people diving back into everything from early 2000s style to the pop hits that defined it. NSYNC's dance going viral again fits right into that pattern. People aren't just discovering something new, they're reaching back for something familiar, and this time BTS helped hand it to a whole new audience.
