And why does it have so many fans and views? I don't think I know anyone who listens to it and the Americans that apparently do I highly doubt they understand Korean.
It's really fucking weird. And some of it even seems directed towards American viewers.
It's pop and has pretty boys which teen/tween girls like. It's DEFINITELY marketed towards western audiences as well since the SK government funds and helps export part what they call Hallyu or "Korean wave" as a way of expressing "soft power" politics.
