Honestly, I don't like kpop. For me, it's very boring.
However, I think kpop is so popular now because kpop producers follow the same method than american/european boybands or girlbands; record companies are in search for young boys or girls who know to sing and dance. Then, those record companies compose music and lyrics for that group of boys or girls and they launch them for the market as a product.
I prefer those bands that compose their own music and write their own lyrics.
I think a lot of kpop songs are actually pretty catchy and they always try to make the choreography to be memorable for audience.
But to me what's most interesting is the way the companies promote their groups. It feels like they want their targeted market (mostly young people) to think that they know these idols personally, when in truth the fans are just seeing what the company wants them to see.
That's the point: the record company gather a group of boys or girls, the same company composes their music and writes their songs, promotes them as the "new sensation" and voilá!, there is a kpop band.
k-pop groups seem very ingenuine to me. Like obviously they have ghostwriters, and its so overproduced. But I do get why people listen to it and why people idolize these groups, but personally I just dont want my bands to be that corporate.
The overall visuals of the groups is pleasing to the eyes.
The dancing is on point. Very synchronized, crisp and clean. They can dance and sing at the same time.
Video production on their music videos are very high quality, colourful and often have interesting concepts.
There is a lot of marketing and promotions, some of the members in the group go on variety shows and youtube to promote their latest releases. At the same time you get to see their personalities come through as well.
For me personally though, I like the fact that they mix other genres into the songs. By doing so you don't also know where the song will go or how it will turn out to be.
The production team is good at pulling off a song with very contrasting and different genres all into one.
Why do I think it's famous? Because the people who produce it create idols out of the stars, and people stick to those idols.
What do I think about it? As a kind of music I personally dislike it, but I especially hate K-Pop due to the horrendous ways in which the idols are treated and how unethical the whole scene is. It's tantamount to abuse and should be shut down or changed for the better.
I'm a cynic, and I think learning about the "mass-production factory line" work behind the scenes gave me a bad impression of that music scene, if you can call it music at that point. I know pop music can be foreboding like that in general, but it gets really bad in the asian pop scene as far as I've learned.
Plus the music itself doesn't really appeal to me one way or another, so hey
