'Massacre' Slays The Billboard 200

J.Lo comes in at No. 2.

50 Cent's "The Massacre" (Shady/Aftermath/Interscope) bursts onto The Billboard 200 with U.S. sales of 1.14 million units, according to Nielsen SoundScan. The figure -- the rapper's best sales week ever -- topples last week's No. 1, Omarion's "O" (T.U.G./Epic/Sony Music), sending it down to No. 8 on a 58% decline to 77,000.

"Massacre" stands as the sixth-largest opening week since Nielsen SoundScan began tracking sales in 1991. Also, as previously reported, 50 Cent breaks his own record for the largest sales total by far of any title with a shortened release week. His previous record for an abbreviated first week came with his first album, "Get Rich or Die Tryin'," which opened with 872,000 in February 2003.

50 Cent leads a quartet of high-profile debuts this week.

Lopez earned her first No. 1 with 2001's "J.Lo" -- which started with 272,000 and has earned 3.7 million to date -– and her second the following year with the remix record "J to Tha L-O!" –- which opened with 156,000 and has a total of 1.4 million.
