All good things must come to an end and it looks like Katy Perry might be the one to stop [article id="1646471"]Eminem's record-setting run[/article] at the top of the Billboard 200 albums chart. As expected, [article id="1644599"]Perry's Teenage Dream[/article] will block [article id="1646449"]Eminem from lodging his eighth week at #1[/article] on next week's Billboard chart by selling 192,000 copies of her second official major label album, or more than four times as many as her first disc, One of the Boys, sold (47,000) in its first week two years ago.

According to figures provided by Nielsen SoundScan, Perry isn't the only one who bested Eminem. Former "American Idol" winner [article id="1646300"]Fantasia bounces back[/article] from a dark personal period that included a recent suicide attempt by landing at #2 with Back to Me on sales of 117,000, which pushes Em's Recovery down to its lowest chart position to date, #3, on sales of 98,000.

There are some other newcomers in the top 10, though, including Usher, whose Versus mini-album comes in at #4 (46,000), followed by country rock act Little Big Town's The Reason Why (42,000), the Randy Rogers Band's Burning the Day (#8, 29,000) and hard rockers the Devil Wears Prada, whose Zombie EP sneaks in at #10 thanks to just under 25,000 units shifted.

The rest of the top 10: Kem, Intimacy (#6, 30,000); [article id="1646937"]Justin Bieber, My World 2.0[/article] (#7, 29,000); and Ray LaMontagne and the Pariah Dogs, God Willin' & the Creek Don't Rise (#9, 28,000).

After a nice run in the top 10 for three weeks, the Arcade Fire's Suburbs falls nine spots to #16 (21,000) as they pass the 250,000 mark, while Usher's five-month-old Raymond v. Raymond disc has a nice resurgence thanks to his new deluxe edition with seven new songs and a remix, surging up 12 spots to #19 as sales pick up by 57 percent to 20,000.

Beloved indie folkie Sufjan Stevens has a strong showing at #27 with All Delighted People (15,000), as do college rock faves Ra Ra Riot, whose Orchard lands at #36 (10,000). Though his single "Cooler Than Me" has lit up the charts all summer, Mike Posner's major label debut, 31 Minutes to Takeoff, has slid steadily down the chart since its debut two weeks ago, falling another 26 spots to #72 as sales dip to less than 6,000.

The news is the same on the iTunes singles and albums charts as Perry took over the pole position on both with the album and the title track single. Em hangs in at #2 on the album tally, followed by the Rogers Band, Fantasia, Mumford & Sons' Sigh No More, Usher's Versus, Stevens, Never Shout Never's Harmony, LaMontagne, and the Devil Wears Prada.

Though iTunes does not divulge sales data, it was a good week for Perry, as her single led a group that was relatively unchanged from the week before, with Taio Cruz at #2 with "Dynamite," followed by Bruno Mars' "Just the Way You Are," [article id="1641027"]Eminem's "Love the Way You Lie,"[/article] Enrique Iglesias' fist-pumping anthem "I Like It," Usher's "DJ Got Us Fallin' in Love," Nelly's "Just a Dream," B.o.B's "Magic," Ke$ha's "Take It Off" and newcomer Kid Cudi with the Kanye collabo "Erase Me."

Perry should be able to retain her perch next week, as the new faces in the crowd include the latest from Disturbed, the Goo Goo Dolls, Fabolous, Papa Roach and Lyfe Jennings.
