The lyrics to Little Big Town's new song 'Shut Up Train' were sparked by exactly what the title suggests. "I wrote it with Chris Tompkins and Hillary Lindsey," songwriter Luke Laird tells Taste of Country. "We wrote it at Hillary’s house out on her porch. It was like the beginning of our co-write, and she lives fairly close to the railroad tracks. We could hear this train, and it was like, ‘Shut up, train!’"
