`` Crazy '' is the debut single by Gnarls Barkley , a musical collaboration between Danger Mouse and CeeLo Green , 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 a lot of 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 -LRB- which no other song had achieved in over ten years , and was only surpassed by Rihanna 's `` Umbrella '' in July 2007 -RRB- 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 . Due to continued download sales , it reached 1 million copies in January 2011 .   The song won a Grammy Award for Best Urban/Alternative Performance in 2007 , and was also nominated for Record of the Year , which it lost to `` Not Ready To Make Nice '' by Dixie Chicks . It was also nominated and further won a 2006 MTV Europe Music Award for Best Song . The song was also named the best song of 2006 by Rolling Stone and by the Village Voice 's annual Pazz & Jop critics poll .  The song was listed at # 11 on Pitchfork Media 's top 500 songs of the 2000s . The song is also in the # 66 place in the list of the best songs ever of Acclaimed Music . In 2010 , it was placed at # 100 in the `` updated '' version of Rolling Stones list of `` The 500 Greatest Songs of All Time '' and ranked at the top position of Rolling Stones top 100 songs of the decade -LRB- 2000 -- 2009 -RRB- . `` Crazy '' was notably performed at the 2006 MTV Movie Awards , with Danger Mouse and CeeLo dressed as various Star Wars characters .
