pop singer-songwriter Destiny Hope Cyrus (born November 23, 1992), better known as Miley Cyrus. “Who Owns My Heart” was released by Hollywood Records as the second single from Cyrus’ third studio album Can’t Be Tamed, in selected European countries. The song was written by Cyrus in collaboration with Antonina Armato, Tim James, and Devrim Karaoglu. Cyrus described it as a “total dance track” with a cool concept. “Who Owns My Heart” was written about the feelings a club’s environment can lead one to believe. Cyrus depicted the club scene to be very sexy, which she thought was primarily composed by the music playing and intense lighting, and thought that it might trigger fake emotions with the person one is dancing with. She stated, “If you’re out, dancing at a club, the way the whole vibe is [...] Do you actually like the person you’re dancing with or is just the whole ambiance of what’s going on?” The song was released on October 22, 2010 in Australia, as a digital single. “Who Owns My Heart” was released in Europe on October 26, 2010 as a CD single.
