Pairing Katy Perry's song Hot n Cold with the coalition's 2013 campaign is not an obvious recipe for success.
The song, better known to Australians as the long-running theme to MasterChef, begins with lyrics like "You change your mind like a girl changes clothes" - hardly an example of the chest-thumping power ballads usually chosen for rousing voters.
Nonetheless, it's the track Tony Abbott told Perry on Thursday he'd choose to help his bid for the country's top job.
"Last time I went to a grand final breakfast I was introduced to one of your numbers Hot n Cold, well maybe that can be my anthem," Mr Abbott told the US pop singer on Sydney's 2Day FM.
Perry wasn't so sure.

"I don't know, I don't know if that's the best song we can pick for a politician," the 28-year-old said from the US.
The storyline of the 2008 hit song is told from a woman's point of view and describes the angst of an unstable relationship.
Its chorus may surprise voters looking for constancy from a potential prime minister, with lines like "You're yes then you're no", "You're in then you're out" and "You're wrong when it's right".
The verses are also not particularly glowing, with Perry singing "Used to laugh 'bout nothing, now you're plain boring" and "I should know you're no good to me".
After deflecting a question about same-sex marriage, Mr Abbott told Perry he was looking forward to her next Australian tour.
"When are you coming back (to Australia)? We need you, we want you," he said.
Perry said she would be happy to meet Mr Abbott "if he lets me in".
Whether the opposition leader realised he'd be using the well-known theme to one of Australia's favourite cooking shows for the coalition's campaign is unclear.
Given MasterChef's recent lack-lustre ratings, it would appear not.
Mr Abbott later told reporters in Launceston it had been a "thrill" to chat to Perry.
His daughter Bridget was jealous about his luncheon date with the singer.
"She wants to crash it," Mr Abbott said.
"My daughters for once were envious of their dad."
He dismissed Perry's criticism of his anti-gay marriage stance saying "good people can respectfully disagree".
