Nicki Minaj is triumphant on Billboard Hot 200 this week, while Madonna suffers a big drop. The Harajuku Barbie soars to the first position, while the Material Girl is knocked off the top spot by posting the largest second-week sale decline in the chart history.

Minaj pushes aside Madge with her newly-released studio album "Pink Friday: Roman Reloaded" which sells 253,000 copies in its opening week. It marks the female rapper's second No. 1 album. She first topped the U.S. album chart when "Pink Friday", which bowed at No. 2 with 375,000, climbed to No. 1 in February 2011.

As for Madge, she falls from the throne of the chart to occupy the eighth place. Her latest effort "MDNA", which became the biggest album debut of the year last week with 359,000 copies sold, only shifts another 48,000 units. It's the biggest second-week drop for a No. 1-debuting album since Nielsen SoundScan began tracking sales data in 1991.

The percentage (down 86.7|percent|) surpasses the record previously set by Lady GaGa with her CD "Born This Way". Last summer, the Mother Monster made a grand entrance on the chart by reigning with a whopping 1.11 million copies before suffering a massive 84.27|percent| drop in sales a week later (174,000).

The other new entries on the top 10 are Rascal Flatts' "Changed" which bows at No. 3, Of Monsters and Men's "My Head Is an Animal" which lands at No. 6, and Marvin Sapp's "I Win" enters at No. 9. The holdovers, meanwhile, are Adele, Lionel Richie, One Direction, "The Hunger Games" soundtrack and Shinedown.
