Anime and K-Pop are considered to be the biggest entertainment exports of their respective countries. It makes sense to combine each medium's individual strengths into something that no fan can resist. As Hallyu, or the Korean Wave, expands across the globe, several Korean artists have contributed to anime OSTs.

Selecting popular artists to perform opening themes is a clever way for the K-Pop genre to continue breaking into one of the biggest music markets around. Legends like BoA and TVXQ and newcomers like Stray Kids, TXT, and ENHYPEN have left their mark in the anime world with their catchy tunes.

In the meantime, however, there have been a few new contributions of anime openings from the world of Korean idols.
