Baby was released by Justin Bieber in 2010 as a single from his album My World 2.0, featuring Ludacris, and quickly became one of the defining pop songs of the early 2010s.

Years later the intro still works as cultural shorthand, instantly placing a clip in that era and signalling light-hearted, mainstream pop nostalgia to audiences who heard it everywhere as teenagers.
