Madonna on track for record sales drop?

Madonna had the biggest album debut of the year with her new offering, "MDNA," but the disc's second week sales may lead to a less flattering record.

Forbes reports that the superstar's latest is on track to have the biggest second-week drop in chart history.

Contributor Roger Friedman is hedging his bets that "when all the numbers are in on Tuesday night, 'MDNA' will have fallen from No. 1 by 88 percent - from 359,000 copies in its first week to roughly 46,000 the second week."

Fans who purchased tickets to Madonna's upcoming tour, which launches May 29, were given the option to purchase the album as part of a bundle, and those sales contributed to Madge's attention-grabbing debut.

“Most of Madonna’s first week sales were CDs that were included in the sale of concert tickets,” Friedman says. “That promotion artificially inflated Madonna’s numbers, putting her first before Lionel Richie and his [new] ‘Tuskegee’ album."

The sales of "MDNA" earned Madonna her eighth No. 1 album on the Billboard 200, but according to Friedman, Richie is the true chart victor.

“In the second week, Richie fell only 47 percent, and sold about 110,000 albums,” he continues, predicting that “‘Tuskegee’ will now finish much higher than ‘MDNA.'"
