K-Pop Redefined

It's not aimed at fans of K-pop. It's a market-expansion play aimed at people who're not yet fans of K-pop, but might be interested if production companies come up with a band that matches their tastes better (and feeding material for an article to Bloomberg is part of that).

The history of K-pop as internationally popular music is a history of looking at what music is popular internationally and emulating that, whether by hiring successful songwriters as advisors, or integrating lyrics in English, Japanese, Spanish, Chinese to target international audiences.

Of course it often doesn't work out, but the investors know that. They're basically VCs, funding lots of long bets and then cutting their losses when metrics aren't on target. That's why there are so many new bands that release a single album and then disappear. Fans of course don't like it, but for the companies it's a purely financial question.
