Rapper Rick Ross has charged to the top of the U.S. album charts with his fifth number one.

Mastermind debuts atop the Billboard 200 countdown with 179,000 first-week sales and becomes the hip-hop heavyweight's first number one since God Forgives, I Don't in 2012.

Ross joins an elite group of rap stars who have at least five number one albums to their name - DMX and Tupac Shakur have five chart-toppers, while Nas and Kanye West have six apiece, Eminem has seven, and Jay Z has 13.

Pharrell Williams debuts at two with his second solo release, G I R L, and the Frozen soundtrack enjoys a sales surge at three, becoming the third album to top 100,000 sales this week.

The soundtrack has now racked up 1.3 million sales since its release late last year (13) and looks set to become the first album to top one million sales in 2014 this coming week - it only needs sales of 6,000 to hit the milestone.

Meanwhile, Glee star Lea Michele's debut album Louder debuts at four with 60,000 first-week sales and country group the Eli Young Band rounds out a week of top five debuts at five with their fifth album, 10,000 Towns.

Ashanti returns to the top 10 for the first time since 2008 as her new release, Braveheart, enters the chart at 10.
