Do you remember the "Gangnam style" by Psy, which was released almost nine years ago in 2012? The K-pop star went viral within a few hours and was a rage for months. However, the generic craze that kickstarted with Psy somehow did not sustain that initial frenzy at a global level.

The scene has been different for Korean pop since then -- particularly bands like BTS that have scaled every high from the Grammys to global countdown charts. Several bands have come up and taken over the world by storm since then. IANS does a recce of the K-pop scene, as the genre continues ruling the globe with its synchronised choreography, hip-swinging hits and good-looking band members.
