Taylor Swift's pop superstardom opened the door for other musicians to get into the Nashville-crossover mood. Upstarts like Kelsea Ballerini and RaeLynn take cues from Swift's honest, romanticism-tinged early work, penning hooky tracks with relatable lyrics. Lady Antebellum and The Band Perry, meanwhile, follow Swift's path of blending country's twangy poetry with pop's charged-up attitude.
