This instrumental was a late addition to True Defiance. It came about when guitarist Patrick Judge and lead vocalist Ryan Clark sat down in the studio with a couple of acoustic guitars and no real expectations. The result was this reflective piece that they decided had to find a place for on the record. Clark told Alternative Press: "I've always appreciated a good stripped-down instrumental track on a metal record. Some of my favorite records have tracks like this--At The Gates' Slaughter Of The Soul, Sepultura's Chaos AD, Metallica's ...And Justice For All and quite a few others. Listening back to it after we'd finished, I feel like it almost has a Kill Bill vibe to it... like a creepy old western. Somehow I think it fits the vibe and flow of the record really well."
The song is played in the key of E so that it segues naturally into the next track on the record, "We Don't Care." Clark explained to Alternative Press: "When we were writing the song, the guitars were in standard tuning. We wanted this song to bleed into whatever came next... almost as if it were the intro to the following song. We realized that the only song on the record that started with an E chord (the root note in this song) was 'We Don't Care.' So essentially, we kept the song in the key of E as a way to line it up with the next song. In short, the song itself is actually the means to an end."
"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.
