'Discipline' puts Jackson back on top

It took some "Discipline" to shake up the top of the album chart.

Janet Jackson ends Jack Johnson's three-week grip on the Billboard 200 as her Island set moved 181,000 units in its first frame. It's Jackson's sixth No. 1 album, tying her with Madonna for second-most chart toppers among female solo acts. Both are chasing Barbra Streisand's record of eight.

Thanks to the fuzzy math that represents today's depressed music biz, "Discipline" outcharts Jackson's previous two records despite far underselling both. 2006's "20 Y.O." and 2004's "Damita Jo" debuted and peaked at No. 2, but the former moved 296,000 units in its first week and the latter scanned 381,000.

Jackson's last visit to the top spot was "All for You" in 2001.

Johnson's "Sleep Through the Static" (Brushfire) drops to No. 3, behind Erykah Badu's first album in four years. Her Universal Motown set "New Amerykah: Part One (4th World War)" debuts with 124,000 units sold for the week ending March 2. It matches the Dallas-born R&B singer's best chart showing; her triple-platinum debut "Baduizm," which hit the chart 11 years ago this week, also peaked at No. 2

Louisiana-born rapper Webbie hits a chart and sales high with "Savage Life 2" (Trill/Asylum), which sold 72,000 to bow at No. 4.

The soundtrack to "Once" gets a meaty Oscar bump this week, jumping two dozen spots to No. 7. The film's "Falling Slowly" won the best song Academy Award.

Elsewhere, Dolly Parton's "Backwoods Barbie" sashays onto the chart at No. 17 — the country legend's highest debut ever.
