Rayna and Deacon have been billed as a legendary songwriting duo, but their latest collaboration may be their best yet from a fan's perspective. "This Time" they've delivered a truly infectious tune.

Featuring Avery (who's been bringing the house down all season no matter who he's with), and epitomizing Juliette's rough-around-the-edges nature, "Trouble Is" would make Miranda Lambert proud.

Chris Carmack gets a lot of credit, not just for taking on a role of closeted gay singer Will Lexington and portraying him with surprising depth, but for holding his own as a country singer. If you heard this on the radio, you'd download it!

Perhaps the single greatest example of the chemistry that made Scarlett and Gunnar so electric to watch. But are they they right one for one another?

Rayna and Luke are both heavyweights, and this track also marked the culmination of Gunnar's songwriting storyline, so "Ball & Chain" had to be an absolute killer. It was.

Like "Ball & Chain," "Wrong Song" had to be a smash for the show to have any musical credibility. It was. The show's initial run of episodes all culminated in this Rayna-Juliet duet, and they delivered.

A Juliette Barnes hit before Juliette Barnes got a whole lot more complicated, "I'm a Girl" is pop country at its finest.

Lennon and Maisy Stella's surprise cover of The Lumineers' hit song shows vocal stylings far beyond their years.

Long defined as part of a duo with Gunnar, at the Opry, Scarlett proved she can hold her own solo and then some.

An underrated Scarlett-Gunnar collaboration, if there is such a thing.

Determined to be taken seriously as an artist and human being, Juliette enlisted none other than Deacon's songwriting services. "Undermine" was the result.
