I’m not sure but this is what I have think happens: the brain loves patterns, it tries to see patterns everywhere. That’s what makes a song catchy. Even in chaos our brain tries to see patterns and images, eg in clouds. So the missing parts of songs and music that our brain fills in is just the brain trying to fill the “pattern” that it see fit so the music is complete.
