The hip-hop icon's new album, which was released at 12 AM this morning (Aug. 29), follows a pair of top-two sets for Wayne in 2010: "Rebirth" (No. 2) and "I Am Not a Human Being" (No. 1). They launched with 176,000 and 110,000 copies, respectively, according SoundScan.

2008's "Tha Carter III" famously debuted at No. 1 with 1.01 million copies sold in its first week, according to Nielsen SoundScan. It is one of only 17 albums to have sold a million in one week since SoundScan began tracking data in 1991.
