Twenty-year-old Meghan Trainor blew up this summer with "All About That Bass," a positive-body-image bubblegum jam that claimed, "I'm bringing booty back/Go ahead, tell those skinny bitches that." Her debut major-label EP hooks similar trickle-down Beyoncé empowerment themes to sugary doo-wop and girl-group melodies. "Title" demands her boy put a name on their relationship status. On "Dear Future Husband," over a melody lifted from Dion's "Runaround Sue," she imagines marriage as a contract between equals who work and don't cook – unless, she implies, he knows how to. It's a YA dream that's no pastel-colored fantasy.
