Bassist John Walker told VH1: "Ryan (guitarist Ryan Ross) and I came home one night - I was living with him while we were recording. We ended up writing a whole song that was a bunch of different parts. And this song is probably about half of that song. We mixed up some parts and redid some parts. Then as we started playing it with the rest of the guys it turned into this."
"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.
