Written by the Veronicas—twin sisters Lisa and Jessica Origliasso—together with Beni Barca and Toby Gad, the track was recorded in Los Angeles, California.

"Popular" received mostly positive reviews from critics, who praised the fun lyrics and named it a highlight of the album.

"[4] Emily Mackay of NME called "Popular" "plain old up-yours fun",[5] while K. Ross Hoffman of AllMusic said the Australian accent was used to "excellent effect" in the rapped verses.
