Miranda Lambert won last week's showdown in a landslide over Kenny Chesney. This week it's a hot new duo taking on an established trio. Florida Georgia Line is watching their second single, 'Get Your Shine On', climb into the top 10 this week, while Lady Antebellum is already in the top 5 with 'Downtown'. We're putting the two songs head-to-head in this week's K-LAW Country Song Showdown. Watch the videos below, then vote for the song you like best.
