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

Sometimes song writing credit is given to an inspiration for a song as well. The Olivia Rodrigo song “Good 4 u” has credit given to the lead singer of Paramore.
