The original, Countless version of "Happier Than Ever" is the title track of Eilish's new album. It presents musically as a straightforward love song but its lyrics — "When I'm away from you, I'm happier than ever" — tell another tale. The new version, however, seems straightforwardly cute. In the video, Billie and The Count subvert the drama at the track's core to bring it back to the friendly vampire's favorite subject: fundamental arithmetic.
Eilish's guest spot on Sesame Street won't air until June 2022, but the new season's first episode will stream starting Thursday, November 11 on HBO Max.
