T.I., the self-proclaimed King of the South, can't get any further north. The rapper's King landed the year's biggest opening week, selling nearly 522,000 copies last week, according to the latest Nielsen SoundScan numbers.

King easily surpassed the year's previous first-week sales leader, Ne-Yo's In My Own Words, which opened to 301,000 copies early last month. T.I. also joins the small circle of rap artists with 500,000-plus first weeks, among them Jay-Z, 50 Cent, Eminem, Kanye West and Nelly.

T.I., who previously peaked at seven with 2004's Grammy-nominated Urban Legend, also charted at the box office this past weekend. His big-screen debut, ATL, opened in third place.

King led a quintet of Top 10 debuts. Checking in at number two was Tim McGraw's Reflected: Greatest Hits Vol. 2, which sold 242,000 copies.

Ghostface Killah landed the next best bow at four as Fishscale weighed in for 110,000 copies. The new disc, which features a full Wu-Tang Clan reunion (the late ODB, included) on the track "9 Milli Bros," nearly doubled the first-week sales of the acclaimed rapper's previous release, 2004's The Pretty Tony Album.

Rob Zombie saw his Educated Horses gallop its way to number five with more than 107,000, while fellow hard rockers Atreyu had its indie release Death-Grip On Yesturday move an astonishing 69,000 copies to open at number nine. The Victory Records act, which is getting radio airplay for "Ex's and Oh's," is currently on the Taste of Chaos Tour and will head out on Ozzfest this summer.

After a slow start, Shakira's second English-language album, Oral Fixation Vol. 2, reentered the Top 10 at six--up 74 spots from the previous chart--thanks to the release of a new enhanced version and an apperance on American Idol. Among other additions, the revamped disc includes the new radio single "Hips Don't Lie" with Wyclef Jean. The album sold 81,000 copies for the week ended Sunday, compared to 11,000 copies the period before.

Meanwhile, the High School Musical soundtrack continues its torrid sales, posting its best selling week so far with 165,000 copies. Although that's up 13,000 from the previous chart, the new releases kept the Disney release at number three.

Last week's chart-topper, Prince's 3121 , fell to number eight on 75,000, down 183,000 copies from its open.

Rounding out the Top 10 were James Blunt's Back to Bedlam at seven and Alan Jackson's Precious Memories at 10.

Just missing the Top 10 was the Yeah Yeah Yeahs, whose new album, Show Your Bones, finished at 11 with 56,000--about 2,000 copies behind Jackson.

The only other notable debuts in the Billboard 200 were Rammstein's Rosenrot at 47, Do or Die's Get That Paper at 159 and the Larry The Cable Guy: Health Inspector soundtrack at 168.

Overall sales were up 1 percent from the previous week and 4 percent about this time last year. Still, 2006 music sales are lagging about 3 percent behind 2005.

Finally, Gnarls Barkley made some musical history by becoming the first artist to top a singles chart entirely on the strength of download sales. The duo, featuring Goodie Mob's Cee-Lo and famed producer Danger Mouse, accomplished this feat on the British charts with "Crazy," the first single from their forthcoming St. Elsewhere debut.
