“It’s incredible,” Pall said of having a No. 1 song. “We work super hard on our music, take it really seriously … to see people enjoying our music like they are, that will never get old. We’re just super grateful.”

As for working with Halsey, he said: “She’s an artist who the last year before we put the song together, we said she was the artist we wanted to collaborate with the most.”
