Familiar yet strangely unfamiliar music has taken over social media. Various K-pop artists are enhancing listeners’ enjoyment by releasing ‘Sped Up’ versions of their songs, and it appears to be gradually establishing itself as an effective strategy in the K-pop market.

ATEEZ, who released a new album last month, YENA, who unveiled her new album on the 11th, and AtHeart, although these three artists differ in genre and agency, they share one common point: all of them have released Sped Up versions of their songs.

A trend that began sweeping the global pop music market about three years ago, Sped Up continues to enjoy strong popularity on social media. By increasing the speed of the original track, Sped Up music transforms the tone and atmosphere into something entirely new.

Sped Up refers to a modified track created by increasing the playback speed of the original song to around 130–150%. It is also referred to by various terms such as ‘Speed Up.’ It rapidly rose in popularity alongside the boom of short-form content on platforms like TikTok and YouTube Shorts, typically under one minute, and is characterized by creating a completely different mood from the original track.

Initially, it was mainly used for challenges and memes, but it has gradually permeated the broader pop music industry and established itself as an independent music format. At the height of its trend in 2023, Sped Up music demonstrated new possibilities across the music industry.

A representative success case is FIFTY FIFTY. Their song ‘Cupid’ went viral on TikTok through its Sped Up version, rapidly gaining global recognition. In addition, EXO’s ‘First Snow’ and HUS (Humming Urban Stereo)’s ‘BANANA SHAKE,’ known for the lyric “나문희의 첫사랑,” also achieved so-called ‘reverse charting’ success as their Sped Up versions spread on TikTok and YouTube Shorts.
 

In this way, Sped Up has emerged as both a strategy for new artists entering the music market and a cultural trend of enjoying existing music in new ways. Accordingly, many agencies are either releasing Sped Up versions of existing tracks separately or unveiling them alongside the official release of original songs.

Recently, attempts in the opposite direction of Sped Up have also been drawing attention, namely, Slowed Down. This format lowers the speed and pitch of the original track to create a dreamy atmosphere and is still in the early stages of gaining mainstream popularity compared to Sped Up. Versions labeled ‘Slowed + Reverb ver.’ are often seen, indicating a Slowed Down track enhanced with reverb effects to produce a richer and deeper sound. Currently, such experimental approaches are particularly noticeable among artists under HYBE and JYP Entertainment.

While Sped Up music tends to evoke responses like “It’s exciting” and “It’s easier to sing along to,” Slowed Down music receives reactions such as “It feels new” and “It’s surprising because it doesn’t sound like the voice I knew,” reflecting a mix of unfamiliarity and freshness. Although there is clearly a listener base that prefers the unique sensibility of Slowed Down, it may take some time for it to reach a broader audience.

From Sped Up to Slowed Down, and beyond. There is growing anticipation for an even richer pop music market where more diverse forms of music coexist.
