With that in mind, one of the slickest choices on this soundtrack is the inclusion of “Telescope,” which on the show is one of Juliette’s big hits; she’s shown filming a big-budget video for it that brings traffic to a standstill, including a car Rayna is driving. Metaphor much?

But that song is also sung by Rayna’s two daughters at a school talent show, the original’s dense pop arrangement forsworn for an acoustic treatment with a lone guitar and handclap percussion. (Seemingly everyone on the show has a daughter or a young sister who’s a fan of Juliette, one of this show’s smart twists.)

Rayna’s daughters are played by Lennon and Maisy Stella, Canadian sisters whose parents perform as the Stellas (they appeared on the CMT reality competition “Can You Duet”); the sisters have a YouTube channel of their own in which they cover songs by moody female singers, including a cover of a Robyn song that verges on a Tune-Yards performance.

Their version of “Telescope” is striking — one of the great performances on the show, and also on the soundtrack. The album also includes the original version sung by Ms. Panettiere, at the end, under the name “Telescope (Radio Mix),” those final two words like a graffitied-on insult. But even though it’s rowdy and sassy and polished — or maybe because of that — it’s great. Not even “Nashville” can derail Nashville.
