Korean Pop Moaty. A bit of an internet phenomenon. I’m too old for the details but my impression is they churn out girl / boy bands manufactured by Svengalis whose whole life is controlled for image. You get cases where, for example, public apologies have been required for having a girl/boyfirend because it spoils the fan bases fantasies of occupying that role.
With it all goes a very stylised fashion / visual image kinda thing, on top of manufactured pop music. One reason among many to be glad to be an auld fecker.
