The HIGH SCHOOL MUSICAL 2 soundtrack has claimed a third week at number one on the U.S. albums chart. The album has become the first disc to spend three weeks at the top of the Billboard charts since country trio Rascal Flatts claimed the number one spot for the same period 18 months ago (06). Christian band Casting Crowns claim the week's highest debut at number two with The Altar And The Door, while rapper Yung Joc's Hustlenomics enters the new countdown at three. Rockers Atreyu crash in at eight with Lead Sails Paper Anchor, and singer/songwriter Ben Harper scores a second top 10 debut with Lifeline at number nine.
