It was released on September 29, 2020, as the lead single from their second studio album The Good Times and the Bad Ones.

The song debuted and peaked at number 37 on the US Billboard Hot 100 chart, becoming the band's first and highest entry.

South Korean boy group AB6IX released a remix of "Fallin' (Adrenaline)" on January 7, 2021.

The visual depicts all five members performing on a drenched stage, sifting through rushing water.

The video is reminiscent of action films, with the members singing from a cell tower that is soon to be struck by godzilla, or atop a jacked up car in a junkyard or even floating mid-air.
