"Undisclosed Desires", also known as "Undisclosed", is a song by English alternative rock band Muse, featured on their 2009 fifth studio album The Resistance. The song was written by lead vocalist Matthew Bellamy, who has described the song as "quite a personal song about me and my girlfriend." "Undisclosed Desires" was released as the second single from the album on 16 November 2009, after "Uprising" in September. It made the UK charts at #49, making it their lowest charting single since "Cave" in 1999, though this could be viewed as a success as there was no physical release and it was not common at the time for a band to have more than one charting single from an album. It has, however achieved large success in Australia where it as since been certified Platinum and is Muse's highest charting single in that country. 　　  　　(wiki)
