PSY is known as a one-hit wonder when it comes to his solo songs, meanwhile BigHit is a one-hit wonder when it comes to creating groups.
edit: I was just stating the similarities.
Gangnam Style = BTS
Gentlemen = TXT
Hangover(ft. Snoop Dog) = Enhypen (collaboration with Mnet)
The one hit wonder thing doesn't mean TXT or Enhypen are flops. That's why I compared him to PSY. Gentlemen and Hangover aren't flops either.
