What is Lost: Definition and 575 Discussions

"Lost!" is a song by the British rock band Coldplay. It was co-produced with Brian Eno and Markus Dravs for the band's fourth album, Viva la Vida or Death and All His Friends. The song was released on 10 November 2008 as the third official single from the album to generally positive critical reviews. A live version was released via download following a performance of the band and Jay-Z at the 2009 Grammy Awards, spurring high digital sales and giving "Lost!" a new peak at number 40 in the United States.
Several official versions of the song exist, including vocalist Chris Martin's separate recording with a piano accompaniment (known as "Lost?") which appears as a B-side for "Violet Hill", and a rap rock version that features Jay-Z (known as "Lost+") which appears on their 2008 EP Prospekt's March. The accompanying music video to the single features a live performance of the band in the United States. Coldplay launched a contest through their website, in which fans submitted self-made music videos. The winning entries were posted on the band's website.
The song was used in the 2010 film The Way, and was also included in NBA 2K14.
