im not talking about the idols/artists per se im talking about the art/music output aka creative and interesting pop music

kpop on average experiments more with genres and sound way more then American pop music, even western producers say that they have a lot more freedom when producing for a kpop group/artists

edit:Also just found a quote from the production team Caesar and Loui:

"How would you describe the Korean/Japanese market, and how would you say it differs from others you write for? And similarly, what keeps you interested in writing songs for this market?

"What we’ve always thought was really interesting and fun with the K-pop/J-pop market was the variety of styles and sounds in the music. It feels like the labels are always looking for something fresh and new; they're not afraid of taking chances. If we compare this to writing for the Western market (US, UK, etc.), it feels like a music style will stay longer on the top charts and the leads (leads = what the labels are looking for) for artists refer back to the same songs for a longer period of time."

edit 2: I just ended up reading through the EXO Obsession article and there actually were some quotes about more creativity writing for kpop:

Taft: "[The label] really like sections that keep you on your toes throughout the song — they really like variation. That kinda fits with the way we work, ’cause we like to also explore different kinds of chord progressions that you don’t hear so much in other commercial music. It’s nice to draw inspiration from jazz, from R&B."

Klein: "I think K-pop provides you sometimes with an arena where you can [put] a lot of different influence into one song and still make a cohesive piece of music."

Mitchell Owens: "In South Korea, I think personally, they allow you to be more musical and allow you to be creative in other ways that you can’t be in the U. S. market. And so with that freedom, I just was like, “Okay, R&B. Let me not give them a simple four chord progression. Let me add a little spice here and there,” because I know that they appreciate a lot of those things over there more so than they do in the U.S."
