Anyone looking for the late Johnny Cash will find him in the Country Music Hall of Fame, the Rock and Roll Hall of Fame, the Gospel Music Hall of Fame, the Folk Music Hall of Fame and many other American music honor rolls.

 But when asked to describe his musical values, Cash preached country gospel: "I love songs about horses, railroads, land, judgment day, family, hard times, whiskey, courtship, marriage, adultery, separation, murder, war, prison, rambling, damnation, home, salvation, death, pride, humor, piety, rebellion, patriotism, larceny, determination, tragedy, rowdiness, heartbreak and love. And mother. And God."

That's the kind of raw, tear-jerking storytelling that country fans embrace, according to author Malcolm Gladwell, in a recent Revisionist History podcast called "The King of Tears." That emotional worldview may be one reason people in different regions and social classes have trouble understanding each other.

"I'm talking about the bright line that divides American society -- not the color line, or the ideological lines. I'm talking about the sad song line," said Gladwell, best known for his work in The New Yorker and bestsellers like "The Tipping Point."

Contrast the worldviews of rock and country, he said. Anyone who studies Rolling Stone Magazine's top 50 rock songs will mainly hear "songs about wanting to have sex, songs about having sex, songs about getting high, presumably after having sex. ... In all of those 50 songs, nobody dies after a long illness, no marriage disintegrates, nobody's killed on a battlefield, no mother grieves for a son."

In terms of raw country emotions, said Gladwell, it's hard to top the epic memorial service after the death of superstar George Jones in 2013. At one point, Vince Gill sobbed his way through the heart of his classic "Go Rest High on that Mountain," with Patty Loveless singing a harmony line alone. That song was inspired by the death of Gill's brother, as well as the death of country star Keith Whitley.
