Miley Cyrus' album sales mark the second-biggest sales week of the year for a female artist, following the 463,000 debut of Mariah Carey's "E=MC2."
Miley Cyrus tops the Billboard 200 with her second No. 1 album "Breakout", which sold 371,000 U.S. copies, according to Nielsen SoundScan. Cyrus' last album, the half soundtrack/half studio set "Hannah Montana 2/Meet Miley Cyrus" started at No. 1 last summer with 326,000.
The first "Hannah Montana" soundtrack, her first recording, also started at No. 1 in 2006, with first-week sales of 281,000. It went on to be the best seller of that year's fourth quarter.
