Shaggy's "Hotshot" (MCA) begins its fourth week at No. 1 on The Billboard 200, after selling another 271,000 copies in the U.S., according to SoundScan. The chart's top-10 was virtually unchanged except for a huge No. 2 debut by the fifth installment of "WWF: The Music," released on the wrestling federation's SmackDown! Records label. The set sold nearly 177,000 units, pushing the Beatles' "1" (Capitol) down to No. 3 on the chart, which will be posted tomorrow (March 1) on Billboard.com.

The post-Grammy sales boom has brought new life to a number of albums, especially Steely Dan's "Two Against Nature" (Giant). The set, which was named album of the year, sold nearly 32,000 units this week, a 747% increase over last week's sales of little more than 3,700 copies. The album also returns to The Billboard 200 at No. 54; it hasn't been on the chart since it dropped off at No. 184 last August.

Also benefiting are albums from Emimem and U2, who each won three awards last week. Emimem's "The Marshall Mathers LP" (Web/Aftermath/Interscope), Grammy's rap album of the year, shoots 62-32 on a sales increase of more than 59% over last week. U2's "All That You Can't Leave Behind" (Interscope) soars 35-11, up more than 75% over the week before.

Best new artist winner Shelby Lynne sees her Mercury album "I Am Shelby Lynne" make its first appearance on The Billboard 200 at No. 165, after a 243% increase in sales over last week. The set had previously topped out at No. 18 on Billboard's Heatseekers chart last February.

Other nominees enjoying huge gains are Paul Simon, whose "You're The One" (Warner Bros.) rises 197-108 with a 93% increase over last week's totals, and Macy Gray, whose "On How Life Is" (Epic) rockets 165-89 on an 88% increase.

Another notable debut comes this week from Chicago instrumental outfit Tortoise, who make their first appearance on the big chart with "Standards" (Thrill Jockey). The album enters at No. 200 and at No. 14 on Billboard's Heatseekers chart.
