Mynx singles this out as a song that has special meaning to him. He told Songfacts: "'Horse' is the true story of dead friend. He lived it. I recorded it. Some people giggle when I play it live. They chuckle at first, then, after the song is finished, they feel awkward around me. They turn away. I dedicate it to Kid. His fingers were like a claw, but he showed up to play bass every night at a seedy den of debauchery with carpeted walls. He believed the song. He was a crackhead when he was younger. He committed suicide on New Years Day. The song is not about him."
The bedrock of David Guetta's Nicki Minaj-featuring single "Hey Mama" is a sample of "Rosie," a 1940s prison recording from folk archivist Alan Lomax that songwriter Esther Dean first showed the French DJ on YouTube.
