About Crazy

"Crazy" is the debut single by American soul duo Gnarls Barkley, taken from their 2006 debut album St. Elsewhere. It peaked at number two on the Billboard Hot 100, and topped the charts in the United Kingdom, Denmark, Canada, the Republic of Ireland, New Zealand and other countries.

The song was leaked in late 2005, months before its regular release, and received airplay on BBC Radio 1 in the United Kingdom, most notably by radio DJ Zane Lowe, who also used the song in television commercials for his show. When it was finally released in March 2006, it became the first single to top the UK Singles Chart on download sales alone. The song remained at the top of the British charts for nine weeks (which no other song had achieved in over ten years, and was only surpassed by Rihanna's "Umbrella" in July 2007) before the band and their record company decided to remove the single from music stores in the country so people would "remember the song fondly and not get sick of it". In spite of this deletion, the song became best-selling single of 2006 in the UK.[7] Due to continued download sales, it reached one million copies in January 2011. In December 2006, it was nominated for the United Kingdom's Record of the Year but lost to "Patience" by Take That.
