Katy Perry proved her singles success is no reverie, as the singer’s sophomore Capitol disc “Teenage Dream” entered the national album chart at No. 1 this week.

Set, which contains the titular chart-topping smash and this summer’s ubiquitous “California Gurls,” shifted 192,000 copies in its first week, according to Nielsen SoundScan figures for the week ended Sunday, Aug. 29.

Perky, buxom vocalist’s 2008 set “One of the Boys” peaked at No. 9, and has sold nearly 1.3 million units to date. New effort has been fired by immense download sales: Pre-album tracks have tallied 4.4 million digital units, signifying a Nielsen SoundScan record since it started tracking sales in 1991.

Fantasia’s “Back to Me” (J Records) took the No. 2 slot, moving 117,000 in its first stanza. Third-season “Idol” winner scored a personal best: Her 2004 debut “Free Yourself” topped out at No. 8.

Singer has been much in the news lately after a suicide attempt early last month and was the recipient of an instant MTV “Behind the Music” episode just prior to album’s release.

After two months in the top or penultimate chart position, Eminem’s “Recovery” (Interscope) dipped to No. 3. Its 98,000-unit total for the week marks the first frame in which rapper’s collection has sold in less than six figures.

Usher’s “Versus” (La Face), a nine-track melange of remixes and new tunes, entered at No. 4 with 46,000 copies sold on arrival. R&B star’s former No. 1 album “Raymond V Raymond” bounced up to No. 19 in a 20,000-unit week (a fat 57% increase), on the strength of an augmented edition that includes “Versus” as a bonus.

Country quartet Little Big Town’s “The Reason Why” (Capitol Nashville) signs on at No. 5 with “The Reason Why,” reaping 42,000 units out of the box. Last set “A Place to Land,” released by indie Equity Music Group, peaked at No. 24.

R&B singer Kem’s “Intimacy” (Motown) falls four rungs to No. 6, tracking 30,000 units (declining 59%). Justin Bieber’s tireless “My World 2.0” (Island) inches up one pole to No. 7 with 29,000 sold, despite a 3% dip.

The Randy Rogers Band settles in at No. 8 with its “Burning the Day” (MCA Nashville), with 29,000 sold. Texas-bred group peaked at No. 29 with its last collection, a self-titled 2008 release.

Ray LaMontagne and the Pariah Dogs’ “God Willin’ and the Creek Don’t Rise” drifts down six notches to No. 9 on a 28,000-unit week (off 57%).

The Devil Wears Prada also scores their highest chart slot yet with its No. 10 debut “Zombie” (Ferret). Five-song undead-themed set moved 25,000 copies, and tops the Ohio group’s No. 11 2009 release “With Roots Above and Branches Below.”

A new “Now” hits compilation and fresh releases from Heart, the Goo Goo Dolls, Disturbed and Lyfe Jennings will be in the running for big debuts next week.
