This song was included on the soundtrack of the third Twilight movie, Eclipse. Frontman Ezra Koenig told The NME that he had a good reason to donate the track. "People have asked us, 'Do you feel like you predicted the vampire trend by naming your band? We said, 'no no no'. But, as time's gone on, the best thing we could do is embrace it." He added that, for fans, the chance to get a new song between albums is pretty sweet. "When it comes to our own album it's a laborious process. Things like this are a low-pressure chance to do something different."
"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.
