Frontman Adam Levine wrote this song after a "weekend bender." He told The Sun September 17, 2010: "I was totally depleted and got home, picked up a guitar and started writing this song. It's my favourite on the record. It's the most honest. It reflects a desperate longing to have somebody in my life, which I didn't at the time."
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."
