The band’s single, Killing In The Name, sold 500,000 downloads beating X Factor winner Joe McElderry’s The Climb by 50,000 copies to clinch the top spot. Their success followed a Facebook campaign designed to prevent another X Factor number one. One retailer said it was a "truly remarkable outcome – possibly the greatest chart upset ever". Speaking on the Radio 1 chart show, Zack de la Rocha from Rage said: "We are very, very ecstatic about being number one." He added it was an "incredible organic grassroots campaign".
