What's behind the ‘K’? Common audio features of Korean popular music before and after the rise of K-POP

Abstract Since its emergence in the 1990s, K-pop has constantly gained popularity and reached a wider audience. K-pop has been described as a blend of different music genres, such as pop, hip-hop, R'n’B and electronic music. However, there was Korean popular music before the rise of K-pop and not all popular music in Korea is K-pop. Using data from Spotify at the track level and exploratory data analysis tools, the paper provides an empirical analysis of the characteristics of Korean popular music since the 1990s and compares K-pop and related genres with Anglo-American pop genres in terms of acousticness, danceability, energy, speechiness and valence. While K-pop is close to the dance pop genre through its danceability, it has on average more energy and cheerfulness than Anglo-American pop. There is also more diversity in Korean popular music than suggested by the K-pop phenomenon. Finally, as K-pop became more successful, it did not become more similar in its audio features to Anglo-American pop.
