The song – cowritten by Miranda Lambert in one mark of Langley’s country bona fides – is an undisputed hit, if charts are how you define such things. Her background is almost too country to be true: The 27-year-old grew up in Alabama, where she was homeschooled until seventh grade for “distracting others.” Fans genuinely love Langley and her flavor of pop-infused country. And “Choosin’ Texas” isn’t just a one-hit wonder: “Be Her,” Langley’s upbeat take on “Jolene” and “I Can’t Love You Anymore,” a collaboration with fellow country music star Morgan Wallen, are occupying No. Now it’s country fans, it’s pop fans.
