Inside the K-Pop Phenomenon That's Taking America by Storm

Bands like BTS are all the rage among fans in the U.S., some of whom can even sing along in Korean.

K-Pop mania is taking over America, with acts like BTS popping up everywhere. 

They sold out their biggest American show at Citi Field in Queens, New York, on Oct. 6, won an American Music Award and are featured on the latest cover of Time magazine. 

Devoted fans know their names by heart and Jin, Suga, J-Hope, RM, Jimin, V and Jungkook, have become new heartthrobs. 

Ahead of the Citi Field show, devoted fans camped out for nearly a week to get a spot near the stage.

One fan told Inside Edition they attended 12 concerts around the world starting in Seoul, South Korea, this year. 

BTS is the best known of the $5 billion K-Pop craze. The South Korean performers were selected for stardom at an early age with strict dance and singing lessons.  

K-Pop became a global phenomenon five years ago after Psy’s “Gangham Style” became a hit. 

And although K-Pop artists sing in their native Korean, American fans still manage to learn the lyrics and sing along.

“With technology it's pretty simple, it's just a Google search to see what their lyrics mean and they're so powerful that once you start you can't really stop, you want to know what everything means," one fan told Inside Edition.
