The groovy fifth track on Coldplay’s dynamic A Head Full of Dreams takes a step into disco, with a simplistic song about life and love, backed by a funky dance floor beat. It features a prominent guitar riff that was inspired by the riff on Guns N' Roses “Sweet Child O' Mine.”

According to bassist Guy Berryman,

[The track] started as a freeform musical session and was called something else, Legends or something. It had a different chord sequence and different hooks and one-by-one things were taken away and things got added.
