Franklin D. Roosevelt's official campaign song was "Row, Row, Row With Roosevelt" but the song "Happy Days Are Here Again" — written for a film — quickly became the lyrical symbol of FDR's promise of a New Deal.
Frank Sinatra changed the lyrics of his 1959 hit "High Hopes" to cheer on John F. Kennedy: "Everyone is voting for Jack/Cause he's got what all the rest lack/Everyone wants to be back/Jack/Jack is on the right track/Cause he's got high hopes."
But these days, campaigns are content to select a safe song that appeals to a broad audience.
Comedian Jon Stewart poked fun at candidate theme songs in a Comedy Central clip that is circulating on the Internet.
Stewart shows video of Obama and Clinton walking into the Democratic National Committee meeting in February. The audio from the "Jesus Christ Superstar" theme song is edited in over Obama's images.
"That's a little on the nose," Stewart jokes. For Clinton's entrance, he plays the rap song "My Milkshake" by Kelis: "My milkshake brings all the boys to the yard."
However, pop culture analysts say candidates usually rely on safe choices.
"Personality-driven politics is going to push you into an inane pop music realm," Heidkamp said.
But Hiatt noted that Presley's music used to be considered controversial, but has now become ubiquitous.
"Maybe in 50 years people will be using [Eminem's] 'The Real Slim Shady' as their campaign song and no one will blink twice."
