Cool Kids was released in 2013 by American indie pop band Echosmith, a group of siblings from California, as a single from their debut album Talking Dreams. The song became a major radio hit in 2014 with its chorus about wanting to belong and be accepted by the popular crowd. Its simple, universal theme kept it in playlists for years and gave it a second life in short video edits, where creators reuse the hook for school, friendship and fitting in stories.
