Before you get downvoted because "cuz evolution," I researched a hypothesis as an undergrad that described a potential social advantage stemming from music perception.

Most primates' social group size is limited, among other things, because you can only keep so many relationships going smoothly. Mutual grooming is probably the most common conflict resolution activity. There are others, but the point one paper made was that they're one-on-one sort of activities. But what if an activity was sound-based? The hypothesis centers on the idea that music, singing, and dancing were critical in exploding the maximum number of humans in any one social group since it gave them all something pro-social that they could do together at the same time.

Think about it: we don't just like music, we share music. We gather in huge arenas to experience the same beats. We have formal dancing as the basis of traditional and romantic social functions. Music can be social glue.

I decided to throw your kid's drawing into Stable Diffusion.
