This bluesy track introduces Marling's second studio album. It's a lonely, lusty tune that ends with two lovers "Eye to eye, nose to nose, ripping off each others clothes in a most peculiar way."
Marling admits the idea came from a time when she tried to salvage a bad relationship. She told Daniel Rachel (The Art of Noise: Conversations with Great Songwriters): "Soon after writing that song I stopped romanticizing situations. It was an embellished situation in my life: the classic unchangeable, awful man."
"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.
