"Superstar" was originally written with English lyrics and titled "Everyday Superstar". When the song was translated into Japanese the lyrics and meaning were completely changed apart from the single word "Superstar". Co-writer Lars Halvor Jensen told HitQuarters that the translator kept it in because "it's a catchy word that everybody understands". The original English language song was recorded by the Irish pop duo Jedward and included on their second album Victory. It was also included as the bonus track on the Japanese release of their debut album Planet Jedward.
"Superstar" was featured in a Seven-net Shopping commercial.
A music video for "Superstar" was shot, but was not included with the CD+DVD version of the single. It was later released on the album Tone. Both the music video's for "Superstar" and "I Don't Know" were included with the Tone as well as their respective dance versions.
The single was released July 20, 2011, and sold 75,687 units on its first day of release. It peaked at #1 on the daily chart and #2 of the weekly chart on the Oricon chart. The single sold over 184,317 copies.Vocals: Tohoshinki (Yunho & Changmin)
