Have campaigns found melodies?

The Democratic National Convention (8 p.m., PBS; 10 p.m., ABC, CBS, NBC) concludes. If all goes according to plan, presumptive nominee Hillary Clinton will address delegates, followed by a balloon drop and confetti. But the real question remains: What song will accompany her big moment?

Clinton campaigned to Rachel Platten’s 2015 “Fight Song” during the primaries. Will this become the official song for the Clinton-Kaine ticket?

According to Pitchfork Media, Sen. Tim Kaine (D-Va.), Clinton’s choice to be vice president, is a Replacements fan. He has cited the Minnesota-based alt-rock band’s 1984 album “Let It Be” as a personal favorite. But perhaps a would-be vice president shouldn’t even utter the word “replacement.”

Campaign songs have been an important part of presidential politics at least since the ditty “Tippecanoe and Tyler Too” was warbled in 1840. Franklin Delano Roosevelt’s campaigns were accompanied by “Happy Days Are Here Again.” Frank Sinatra reworked the song “High Hopes” for Kennedy’s 1960 campaign. A fan of “Up With People” and the wholesome sound of young glee clubs, Richard Nixon used the unabashedly “square” song “Nixon Now” to appeal to his “silent majority” in 1972. It worked. In 1988, candidate Michael Dukakis emphasized his immigrant roots with Neil Diamond’s “America.” That didn’t work as well.

Last week’s Republican National Convention had its share of musical mishaps. The Trump campaign used four songs — Queen’s “We Are the Champions,” the Rolling Stones’ “You Can’t Always Get What You Want,” the Beatles’ “Here Comes the Sun” and Free’s “All Right Now” — all without permission, earning stern rebukes from representatives of the artists living and dead.

This is nothing new. In 1984, there was some confusion about Bruce Springsteen’s “Born in the USA.” George W. Bush used Tom Petty’s “I Won’t Back Down” in his 2000 campaign, until the singer told the campaign to cease and desist.

Trump’s convention playlist leaned pretty heavily on so-called classic rock. He’s hardly the first to tap that genre. Candidate Bill Clinton’s balloon drop was accompanied by Fleetwood Mac’s “Don’t Stop,” a song that would repeat throughout the campaign. To some, that 1977 song was already an “oldie” when it was revived in 1992, some 24 years ago.

So what song will Hillary choose? Will it look forward or backward? Will we hear it once and forget it? Or will it become part of political and musical history?
