Gnarls Barkley Going 'Crazy' In The UK

Still a month away from being released in the US, Gnarls Barkley (a collaboration between Danger Mouse and Cee-Lo) is already making headway in the UK, with the single "Crazy" set to become the UK's first number one single based on download sales alone. Only until this month, could download sales count towards a chart position, as long as the following week, physical copies of the single go on sale. Previously, download sales could only count towards a chart position if the release was also available to buy in stores.
