Why do many pop songs have so many different songwriters listed?

Question

I see so many songs with 3-5 or more listed in the credits. I always thought sometimes one person wrote music, and another wrote lyrics. Why can it take around 5 people to write a song?

Answer 1

because theyre not artists. theyre a group that was put together because thats what the labels research suggested people liked and wanted. they dont have talent. theyre groups by committee.
