Twang, clang, harangue

Nashville

(Fox, 9 p.m. Fridays)

More or less real people struggle to make it in country music in the city where people really do struggle to make it in country music. From Go Go Luckey Productions (“Laguna Beach,” “Rollergirls”), where reality always looks pretty, even when it isn’t. (Isn’t real, isn’t pretty.)

Jail

(MyNetwork, 9 p.m. Tuesdays)

The drunk, disoriented and petty criminals are seen cooling their heels, waving their arms and even keeping their sense of humor in well-scrubbed and overlighted lockups from coast to coast. A kind of sequel to “Cops,” from the man who brought you “Cops.” Also airs on Court TV under the awkward title “Inside American Jail.”

Decision House

(MyNetwork, 8 p.m., Wednesdays)

Barely married couples spent three days in reality television to decide whether to stay together in this yell-at-the-set series. Judge Lynn Toler of the syndicated “Divorce Court” presiding.
