Hip-hop supergroup Slaughterhouse had a [article id="1692930"]simple message[/article]
 to their fans: Go out and buy our album for the sake of hip-hop. And they did, helping Eminem's labelmates land at #2 on next week's Billboard 200 chart thanks to sales of nearly 52,000 copies of Welcome To: Our House, according to figures provided by Nielsen SoundScan.

They were blocked from the top spot, though, by Christian rocker/rapper TobyMac, who scored the first #1 debut for a Christian act since 1997 when Eye On It sold just under 69,000. The other new entry in the top 10 came from veteran singer Alanis Morissette, whose [article id="1692737"]Havoc and Bright Lights[/article]
 bowed at #5 on sales of 33,000.

The rest of the top 10: last week's #1, Trey Songz's Chapter V (#3, 41,000), NOW 43 (#4, 41,000), Maroon 5, Overexposed (#6, 31,000), [article id="1693181"]VMA performer 2 Chainz[/article]
 Based on a T.R.U. Story (#7, 29,000), Carrie Underwood Blown Away (#8, 28,000), Fun. Some Nights (#9, 25,000) and, after its first-ever week outside the top 10 Adele 21 (#10, 23,000).

According to Billboard, 21's 79 nonconsecutive weeks in the top 10 is the third-longest run of its kind since 1963, bested only by Bruce Springsteen's Born in the U.S.A. (84 weeks) and the soundtrack to "The Sound of Music" (109).

Hip-hop matchmaker DJ Khaled's Kiss the Ring took a tumble from its #4 throne, as second week sales slipped by 64 percent to 15,000 and it slid 13 spots to #17.

Rounding out the top 10: Justin Bieber, "As Long As You Love Me," Phillip Phillips, "Home," Neon Trees, "Everybody Talks," Cher Lloyd, "Want U Back" and Jepsen's "Call Me Maybe."
