SEAN KINGSTON's summer hit Beautiful Girls continues to set the pace at the top of the U.S. charts, claiming a fourth week at number one. The Stand By Me revamp tops the new Billboard Hot 100, while Fergie, Timbaland and Plain White T's stay fixed to numbers two, three and four. Meanwhile, the U.S. domination of TV phenomenon High School Musical 2 continues on the singles chart - six tunes from the television movie's hit soundtrack have scored Billboard Hot 100 places. A day after the soundtrack debuted at number one on The Billboard 200 albums chart, Zac Efron and Vanessa Anne Hudgens' You Are the Music In Me duet is the Hot 100's highest debut at 38. The song is the best-selling track of nine High School Musical 2 songs on the new chart, including cast track What Time Is It, which jumps from 35 to 33. Elsewhere, the Eagles claim the top debut on America's Hot Country Songs - at 44 - with How Long. It's the first time the classic rockers have been on the country countdown for 13 years.
