The rapper previously reached No. 1 on Billboard's top 200 chart in 2008 with "Trilla." He also notched No. 1's with 2006's "Port of Miami" and 2009's "Deeper Than Rap."
According to Billboard, Ross has more No. 1 albums than Lil Wayne and Snoop Lion (formerly known as Snoop Dogg), but he has a long way to go before he catches up with Jay-Z, the leading rapper with 12 chart-topping sets.
Last week's chart-topper, Zac Brown Band's "Uncaged," fell to second place, followed by Justin Bieber's "Believe" in third.
