You need people to work together today in order to overcome the time it takes
This was also done before with members of the studio doing certain portions, or say one artist does the backgrounds the other the people

Now if you got 10 people together you could easily make many but selling them is another thing still and now you have to split the cash so volume would have to happen

You forget too that some of these artists weren’t paid a ton for them compared to what they sell for because they’re famous

Oh lol and good luck getting that many artists to work together
You have to curate a group like a band of musicians
