Have you heard Little Big Town’s single, “Girl Crush”? If not (I hadn’t), let me break it down for you. A tale as old as time: Girl dates boy. Boy and girl break up. Girl channels boy’s new girlfriend as to satiate the sensations lost post-breakup. It’s co-written by Stoughton-based Lori McKenna. It’s a fun little ditty. And despite what its name implies, the song’s tone appreciates envy, rather than desire.
