On July 16 1985, Madonna’s hit single, Crazy For You, was certified gold by the Recording Industry Association of America (RIAA) for shipment of one million copies of the single in United States—the requirement for a gold single prior to 1989.
According to the book Risky Business: Rock In Film, the single has sold two million copies in the U.S., making it one of her biggest selling physical singles, behind Vogue and Like A Prayer. The lack of any further certification to verify this figure is plausible considering Crazy For You was released through Geffen Records; because Madonna was not a Geffen recording artist they would have had little incentive to invest in additional certifications once the initial promotional push for the soundtrack had ended.
