I've thought about it slightly and without Teddy Park there is no blackpink, but without the individual members each bringing their own flavour to the group, there is no blackpink either.
If you're familiar with the concept art industry, this is essentially just character design but with living people.
We are being fed a story, Katy Perry and Ariana Grande are good examples of this.
Ariana Grande has written a few of her own songs (though none of these were released as singles).
Perhaps you meant that neither Katy Perry or Ariana Grande are composers (who write the instrumental portion of the song)?
"Kayfabe, in the United States, is often seen as the suspension of disbelief that is used to create the non-wrestling aspects of promotions, such as feuds, angles, and gimmicks in a manner similar to other forms of fictional entertainment. In relative terms, a wrestler breaking kayfabe during a show would be likened to an actor breaking character on-camera."
Outside of the entertainment industry, politics is an obvious example, though wikipedia states:
"It has long been claimed that kayfabe has been used in American politics, especially in election campaigns, Congress, and the White House, but no evidence of actual usage of kayfabe in Washington has ever been uncovered. In interviews as Governor of Minnesota, former wrestler Jesse Ventura often likened Washington to wrestling when he said that politicians "pretend to hate each other in public, then go out to dinner together.""
I find the idea of being fed a story fascinating because a successful story feels more real than life itself and I'm not sure you can separate the two (life and the stories we tell ourselves). Once you can see it for what it is, that it's just a story, it breaks the illusion. But a really powerful story sucks you back in time and time again, and sometimes, you forget that you were being told a story in the first place.
And now after typing the above paragraph I sit wondering how many stories I currently believe are real, are just stories after all. Money being one of the most powerful.
I think most people think she falls under this category.
Who doesn't consider choir members to be artists?
Why do you need to be a writer to get royalties. Would the producers not be able to ask for a royalty regardless?
Many record producers do participate in the songwriting or composition process and are credited for that work (for example, Jay-Z), but the vast majority don't (for example, Glen Wallachs, co-founder of Capital Records).
Production can mean anything and everything from project management, sound design, co-writing, arranging to hands-on instrumental parts - to turning up once a week and saying "Sounds great. Carry on."
The split depends on the producer/artist agreement.
Session musicians don't usually get points even though they may literally write their parts. In publishing terms a song is melody+lyrics, and everything else is work-for-hire arrangement.
This often gets renegotiated because it's clearly nonsense. But that's the starting point.
A producer cannot "negotiate" creative credit if they did not earn it, because the guilds will not allow it.
If a producer wants writing credit, they must earn the writing credit by performing creative activities as specified by the guild rules. Project management and other "producing" activities do not count. Note however that the creative contributions of session musicians under WFH arrangements are generally attributed to their employer--i.e., to the producer, and SCL rules generally apply to determine the creative contribution the producer may claim for the work of session musicians.
Co-writing and arranging are not "producing" activities, they are writing and composition activities which can qualify for songwriting and composing credit. Few producers participate creatively in their songs, but the ones that do tend to be the more famous ones (like Dr. Dre, Jay-Z, Dr. Luke, etc.) and are use usually artists in their own right.
It is all evil but it kind of shows who has the negotiation leverage. Todays pop music scene is all about creating a celebrity image consumers want to identify with. Once said image is created the actual music is not that important. So the writers do not get much credit.
