Two Hearts (Kish Mauve song)

"Two Hearts", alternatively titled "2 Hearts", is a song first recorded by British electronic duo Kish Mauve, written for their 2005 self-titled extended play and later re-recorded by Australian singer Kylie Minogue for her tenth studio album, X (2007).

Though the song was released in North America, it did not manage to chart on any component Billboard charts in the United States, but it did chart in Canada, peaking at number 60. The music video for "2 Hearts" was directed by Dawn Shadforth and filmed at Shepperton Studios in London, England. It features Minogue performing the song on a stage, where she dances on a piano and features the band playing along with the song.
