David Keenan told Songfacts the story behind this song, which appears on his debut album, A Beginner's Guide To Bravery. "The song 'Origin Of The World' centers around Gustave Courbet's painting of the same name and a story from Greek Mythology where this fella Actaeon is out hunting with his hounds and he spies the goddess Diana bathing in a sacred pond," he said. "She turns him into a stag with a splash of the water and his own hounds eat him alive. It embodies a sense of wonderment and exploration, the ideal and the metaphor of love being a risky enterprise where one could be consumed by loss at any time if the heart is confiscated and discarded by the other. Wish me luck, I'm in trouble again. It's the element of danger that draws us back to the source. The hunt before the kill, as the saying goes."
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.
"Whole Lotta Love" was Led Zeppelin's only US Top 10 hit, charting at #4. Many of their songs, including "Stairway To Heaven," were not released as singles, as it was considered bad form in England to make people pay for singles that were on albums.
