Miley Cyrus will land her second No. 1 album on The Billboard 200 tomorrow (July 30), as "Breakout" (Hollywood) bows with 371,000 U.S. copies, according to Nielsen SoundScan. That's the second-biggest sales week of the year for a female artist, following the 463,000 debut of Mariah Carey's "E=MC2" (Island/IDJMG).

Cyrus' last album, the half soundtrack, half studio set "Hannah Montana 2/Meet Miley Cyrus" (Hollywood/Walt Disney), started at No. 1 last summer with 326,000.

The first "Hanna Montana" soundtrack, which launched her recording career, also bowed 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 with less than three months of shelf life.
