Lil Wayne's Tha Carter, although leaked on the Internet days before its release on Aug. 29, sold 964,000 copies and made it to the chart-topper on Billboard 200 chart, according to Nielsen SoundScan.
In Lil Wayne's career so far, this is the third time that his music is hitting the Billboard 200 chart.
The week also saw the top 10 debut of the Red Hot Chili Peppers' I'm With You (No. 2 with 228,000), David Guetta's Nothing But the Beat (No. 5 with 56,000) and Jake Owen's Barefoot Blue Jean Night (No. 6 with 55,000), according to a report in USA Today.
Before Tha Carter IV, Lady Gaga's Born This Way sold 1.1 million in May with a boost of a two-day 99-cent promotion on Amazon.
Tha Carter IV, which was released after midnight on Aug. 29, broke iTunes' one-week downloads record with 345,000.
He is a superstar with an incredibly huge following. The brand name 'Carter' holds a lot of weight when you see it next to Lil Wayne in much the same way as 'Blueprint' does with Jay-Z. You expect quality and creativity, USA Today quoted Keith Caufield, Billboard's associate director of charts/retail as saying.
Tha Carter III in 2008 had sold 1 million plus copies with its debut and has totaled more than 3.7 million.
Most of the last year was spent by Lil Wayne in a New York prison on gun charges and in spite of that, Tha Carter IV loomed.
