The chorus of the song uses a recurring melody piece from "Jefferson", a Roxette song from their Room Service album (2001). The writer of "Jefferson", Per Gessle, made an arrangement with Groove Coverage to receive a rumoured 50% of royalties from the song, though Gessle said that figure was "...far from the truth." Gessle is listed as one of the song's official songwriters/composers on BMI's website.
"God Is a Girl" was very successful in Germany and Austria. "God Is a Girl" reached number 1 in China and there were 1.5 million legal downloads – an absolute coup for an international artist in China.
