Ashley Monroe's sound is classic Nashville. Her lyrics? Not so much. The Tennessee native's feather-ruffling breakout hit, "Weed Instead of Roses," suggests pot, heavy metal and "whips and chains" as a way to spice up a boring marriage, and her excellent new album, Like a Rose, features country's first Fifty Shades of Grey reference. "I only write about things I know," she says. "I met Willie Nelson the other day, and I was like, ‘Man, Willie, you smell incredible.'"
