There are more suds this year in TV’s frothiest soap opera with a twang, as rivalries heat up and relationships get even hotter. Beyond the dramatic twists and turns, music remains as strong and clear as a Tennessee church bell. Functioning almost like a record label, the acclaimed series has already generated several real-life hit songs on country radio. The first season’s soundtrack, released in two volumes, sold an impressive 2.6 million digital downloads. Now the stars of the series are back with more of the best new country music around. Connie Britton sings about love’s complications on the driving “Ball and Chain,” while Hayden Panittiere courts danger on the feisty “Trouble Is.” Duets on the album include Clare Bowen and Sam Palladio singing the tender “Why Can’t I Say Goodnight” and Canadian sisters Lennon and Maisy Stella harmonizing sweetly on “A Life That’s Good.” And newcomer Chaley Rose delivers a stunning acapella rendition of “Wayfaring Stranger,” ensuring that Nashville stays fresh with bold new talent.
