'Liar Liar' by Captain Ska was released on Friday and by Monday it has risen to number two on the influential iTunes singles chart.
The song features sound bites from Theresa May, alongside lyrics including: "She's a liar liar, you can't trust her, no, no, no."
Major music outlets have rejected requests to play it but fans have been snapping up the single regardless.
A version of 'Liar Liar' was released in 2010, with a new edition recorded for the 2017 election.
Some radio stations declined to play the song because of laws governing impartiality during the election campaign.
However, Ofcom, the TV and radio regulator, said broadcasters must show impartiality.
Theresa May had called for an early general election on June 8 in April. She had said that it is the only way to guarantee political stability in the UK for years after it leaves the European Union.
