Let’s be honest:
In 2025, TikTok is the new music chart.
If your song isn’t trending with a challenge, an edit, or a sped-up dance remix… did it even exist?
K-pop and J-pop idols know this.
They’re dropping teaser-friendly intros, choreo hooks made for 9:16 screens, and even baking TikTok filters into their comebacks.
This year? Some songs exploded overnight.
Others took a single fancam, a fan edit, or a meme — and boom, 10 million videos later, they’re the soundtrack of the internet.
So here it is:
The top viral K-pop & J-pop songs on TikTok in 2025.
The ones you heard 200 times and still didn’t skip.
