Andreas "Quiz" Romdhane and Josef Larossi co-wrote this. Among the other songs the Swedish production duo have credits for are "Up" for British girl group The Saturdays, "Ride It" for Geri Halliwell and a lot of Il Divo's material.
The Frozen song "Let It Go" was recorded in 42 different languages for the movie's foreign releases. This earned it an entry in the 2016 Guinness World Records publication for "Most Languages Featured on a Single."
"(What's So Funny 'Bout) Peace, Love, and Understanding" was written by Nick Lowe in 1974. The original version with his group Brinsley Schwarz was kind of somber, but Elvis Costello made it a classic with his 1978 uptempo take.
