For a third week in a row, Disney's "High School Musical 2" soundtrack is No. 1 on The Billboard 200, the first album to do so since Rascal Flatts' "Me and My Gang" in early 2006. "HSM 2" sold 210,000 copies in the United States, according to Nielsen SoundScan, a 43% decline over last week. The album has already shifted more than 1.19 million units since its release.
