Nashville songwriter Dallas Wilson knows his way around the human heart. He depicts undying devotion on the Dylan Scott smash “Nobody” just as convincingly as he turns out a tongue-in-cheek kiss-off tune like Mitchell Tenpenny’s “Bitches,” bringing a sinuous R&B sensibility to his country template. On “Small Town, Girl” by Lainey Wilson (no relation), he shows his subtle side, gradually unveiling a sardonic tale of a scorned woman’s vengeance.
