2 Chainz borrows the flow from Juvenile's 1998 Hip-Hop classic tune "Back That Thang Up" for this song. Drake previously interpolated some of the lyrics of Juvenile's explicit cut on his Take Care track "Practice."
"Back That Thang Up" was produced by former Cash Money in house producer Mannie Fresh and the veteran New Orleans native also supplied the beat for this song, which uses his home city's bounce music as its backbone. Mannie Fresh created the entire instrumentation on an iPad.
2 Chainz traveled to New Orleans' 7th Ward section for the Marc Klasfeld directed video. The clip reunites the Hot Boys members Lil Wayne, Juvenile and Turk, whom we see partying with the Big Easy locals. The only member missing from the hip-hop group is B.G., who is serving a 14-year sentence for weapons possession, though his presence is felt with the "Free B.G." T-shirt that the Atlanta rhymer is wearing.
"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.
"Sloop John B" is a traditional West Indian folk song, and it was a huge hit for The Beach Boys in 1966. They tweaked the lyric, "This is the worst trip since I've been born" to "...I've ever been on" as a wink to acid culture.
