‘High School Musical 2’ still rules the school

Four albums debut in the Top 10 of the national sales chart this week, but none came close to dethroning the soundtrack to Disney’s “High School Musical 2.” The album sold 210,000 copies, pushing its total to nearly 1.2 million.

Only one other album topped 100,000 sales last week, and it comes from Christian act Casting Crowns, whose third set “The Altar and the Door” sold 129,000 copies in its first week in stores.

Southern rapper Yung Joc is at No. 3 with “Hustlenomics.” His sophomore album sold 69,000 copies.

Orange County metal act Atreyu earns its second Top-10 showing with its major label debut, “Lead Sails Paper Anchor,” arriving at No. 8 after selling 43,000 copies, according to Nielsen SoundScan.

With no powerhouse releases this week, “HSM2” has a shot at holding onto the top spot for a fourth week, before the industry’s fourth quarter sales push kicks off Tuesday with new albums from Kanye West, 50 Cent and Kenny Chesney.

If “HSM2” does log four weeks at No. 1, it would be the first album to do so in almost 2 1/2 years. The last to make or break a month at No. 1? 50 Cent’s “The Massacre.”
