High Quality Content by WIKIPEDIA articles! Crazy is the first single from Gnarls Barkley, a musical collaboration between Danger Mouse and Cee-Lo, and is taken from their 2006 debut album St. Elsewhere. It became a top ten hit throughout Europe, North America and Australia, in the first half of 2006, reaching number one of the single charts in the United Kingdom, Ireland, Denmark, Canada, New Zealand and other countries. The song was leaked in late 2005, months before its regular release, and consequently received massive airplay on BBC Radio 1 in the United Kingdom, most notably by radio DJ Zane Lowe, who also used the song in TV ads for his show. When it was finally released in March 2006, it became the first single to top the UK charts on download sales alone. The song remained at number one in the UK Singles Chart 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 UK stores so people would "remember the song fondly and not get sick of it."
