Why K-pop groups like BTS and Blackpink aren’t the only ones who top South Korea’s charts – ballads, K-drama OSTs, trot and hip-hop also vie for supremacy
- Solo artists IU and trot singer Lim Young-woong topped charts in South Korea for most-streamed and most-downloaded songs in 2021
- The success of shows like Itaewon Class drives interest in their soundtracks, which are also responsible for catapulting many a new artist to stardom

Recent years have seen South Korean pop music acts achieve global popularity on a scale never seen before – especially in 2021. But while outside Korea it may seem like all the country has to offer is energetic K-pop “idol” boy bands and girl groups, the local scene is more complex, with hip-hop, ballads and solo acts fighting for supremacy among Korean listeners.
“While K-pop, focusing on dance music, has been popular [internationally], in Korea there are several different popular music genres, including ballad, [K-]drama original soundtrack, rock ballad, R&B and trot,” says Dal-yong Jin, director of The Transnational Culture and Digital Technology Lab at Simon Fraser University in Canada. Trot is a popular music style in the country developed in the 1900s known for its distinct rhythms and singing styles.
“Among these, ‘ballad’ has been the most popular,” Jin says. “Korean people like this particular music genre [because it] represents people’s daily lives and contemporary society.”

In fact, music from non-K-pop idol groups was at No. 1 on the South Korean charts for both most-streamed songs and most-downloaded songs in 2021, according to chart-tracker Gaon.
