In the second week of release, the Miley Cyrus album 
Breakout sold 158,467 copies which places it #2 on the chart.  In two weeks 
Breakout has sold over 500,000 copies.
The top two albums flip-flopped this week with Sugarland's 
Love On the Inside taking the top spot this week in part to the release of a special deluxe edition of that CD.
