Madonna‘s “MDNA” album had the biggest second week drop in chart history last week according to Forbes.

“Wow. The first week’s sales, as I revealed exclusively (and then the New York Post lifted it from us), most of Madonna’s first week sales were CDs that were included in the sale of concert tickets. That promotion artificially inflated Madonna’s numbers, putting her first before Lionel Richie and his “Tuskegee” album. In the second week, Richie fell only 47% and sold about 110,000 albums–which is normal. “Tuskegee” will now finish much higher than “MDNA.” I do think that all the people involved in the Madonna ticket-CD deal should apologize to Richie for denying him his rightful place at number 1, starting with Billboard and SoundScan. But Richie’s consolation is that he has a major hit, while “MDNA” is a total dud. So far, “MDNA” has not produced anything like a hit single either, no radio play or anything to provide organic promotion. But Madonna’s concert tour with Live Nation will be a big hit, so it’s not like we have to worry about her financial situation.”
