Official numbers won’t be available until Wednesday, but it looks as if Madonna’s new album MDNA will break records with the biggest second-week sales drop in chart history.

As Forbes reports, MDNA sales will have dropped from 359,000 copies sold in its first week to about 46,000 in its second week. That’s an 88 percent drop.

Forbes reporter Roger Friedman also mentions that Madonna’s first-week sales may have been inflated because many of those CDs were included in the sale of the singer’s concert tickets.
