“100” is the first promotional single from SuperM’s debut full-length album Super One, accompanied by a music video upon release.

In an interview with Billboard published on August 14th, 2020, Mark revealed the title is a reference to their “100% energy” and Lucas was more specific in an Instagram post just a few days later when he said that their performances and music both “go one hundred.”

Produced by K-Pop newcomer Alawn, the track resembles the punchy yet smooth sound heard in NCT 127’s “Punch,” WayV’s “After Midnight,” and VICTON’s “Mayday.”
