Meghan Trainor is known for her hard-to-ignore persona—an empowered bombshell who celebrates herself for “being no stick-figure Barbie doll” and brings a decidedly feminist vibe to catchy pop. Her skillful, stylized approach to performance is matched by songwriting savvy. A Berklee-trained musician who penned songs for the likes of Rascal Flatts before emerging as a solo star in 2014, Trainor deploys clever double entendres and artful references—using the winking vernacular of classic girl groups in a body-positive anthem, for instance—to put a fresh spin on retrofitted R&B-flavored pop.
