This song references a glass mausoleum built by 19th-century eccentric Horatio Bright to house his dead wife and son ("If you stare through the glass from moment to moment. It's funny what you find").
The song includes both a Mellotron and Nancy Kerr's viola. Hawley told Uncut: "The Mellotron is a lovely sound. It has a unique sound all its own, nothing really like strings, but Nancy put emotion back into the party."
"Crank That (Soulja Boy)" was the most successful digital track of 2007 in the US with 2,909,000 downloads. On January 6, 2008 it became the first song ever to sell 3 million digital copies in the States.
