John Legend is modern R&B's classiest male singer, bringing old-fashioned suavity to hip-hop soul; the Roots are the world's most versatile (and maybe best) band. Together, they have made a brilliantly conceived and executed album, reviving music from the Nixon-era heyday of politically engaged R&B. Bustling through funk, Philly soul and gospel, taking on songs famous (Marvin Gaye's "Wholy Holy") and obscure (Mike James Kirkland's "Hang on in There"), Legend and the Roots capture the old feeling of protest and uplift while updating the sound. They're not imitators — they're heirs.

“(We're Not) The Jet Set”

George Jones and Tammy Wynette were still married when they recorded the tongue-in-cheek "(We're Not) The Jet Set." The lyrics, written by Nashville songwriter Bobby Braddock, who also penned Wynette's "D-I-V-O-R-C-E" and Jones' "He Stopped Loving Her Today," make fun of the good life by declaring, "We're not the Jet Set/We're the old Chevrolet set." Braddock recalled that while writing the song, he needed the name of a city that evened out the rhyme he had with "Riviera" and "Missourah." “I got out a Rand McNally atlas," he said. "In the first part are the maps. The last part is an alphabetical listing of cities. I wanted a rustic, small-time sound. I went to the listing for Missouri. And I found 'Festus.' I loved the sound of it."
