CMT’s seminal music series, CMT Crossroads, notched its highest ratings in more than five years with the pairing of pop group Backstreet Boys with country duo Florida Georgia Line. The episode, which aired Wednesday, Aug. 30, became the highest-rated Crossroads among Adults 18-49 (.21) and Women 18-49 (.34) since another cross-genre mashup with Steven Tyler and Carrie Underwood in 2012 (Nielsen Live+3).
