Chart performance ''-themed performance of the song at the
2006 MTV Movie Awards. In the United Kingdom, following its release as a digital download on March 13, 2006, the song debuted at the number-one spot on the
UK Download Chart on March 22, 2006. At the time, chart rules allowed a song to appear in the
UK Singles Chart based on their download sales if a physical equivalent was to be released the following week. "Crazy" became the first number-one single in the United Kingdom based on download sales alone (more than 31,000 that week), on April 2, 2006―for the week ending date April 8, 2006 The following week, "Crazy" was at number five, before disappearing completely from the chart a week later, as under chart rules a physically deleted single could not remain on the chart longer than two weeks after deletion date. Thus, "Crazy" made history at both ends of its chart run. It marked the most rapid exit from the British chart ever for a former number one, and number five was the highest position at which a single has ever spent its final week on the chart until
Alex Day's "
Forever Yours" fell out from number four. In the first week of 2007, "Crazy" recharted at number 30, based purely on downloads. The chart rules had been changed yet again, allowing any sold song to chart, irrespective of whether or not it was still on sale in stores. Due to continued download sales, the single became a million-seller in January 2011. It was the 104th single to do this. During its long stay in the British charts, the single also entered multiple other single charts throughout Europe, including the German, the Swedish, the Austrian and the
Irish Singles Charts, and the
Dutch Top 40, resulting in a number one position on the
European Hot 100 Singles. "Crazy" also performed strongly outside Europe, with top-five positions on the New Zealand and
Australian Single Charts, and was also certified
gold in both countries. On May 29, 2006, the single went down in New Zealand music history by becoming the 500th number-one single in New Zealand since the official top 40 chart was started in 1973. The Discount Rhinos Full Control remix of the track also featured in the top 20 of the Australian ARIA Club chart. When the album
St. Elsewhere was released in the United States on May 9, 2006, the song had debuted at number 91 on the
Billboard Hot 100. The song reached the top 40 on May 23, 2006. In mid-2006, "Crazy" spent seven consecutive weeks in the number-two spot. It became the year's first single to peak at number two and never reach number one. The song also charted well on other charts, hitting number seven on the
US Modern Rock chart and number 53 on the
Hot R&B/Hip-Hop Tracks. It was certified eight-times Platinum by
RIAA. Throughout 2006, it sold 1,629,467 digital copies. As of June 2013, the song has sold 3,401,000 downloads copies in the United States. ==Music videos==
