Nelly Furtado took the No. 1 spot on the charts this week -- a first for the Canadian singer -- with her latest album, 'Loose,' selling 218,000 copies. She unseated Busta Rhymes, who dropped to No. 5, selling 68,000 copies of 'The Big Bang,' according to Nielsen SoundScan.

Furtado's  success was no doubt spearheaded by the album's first single, 'Promiscuous,' which features beatmaster and mega-producer Timbaland.

Christian metal rockers Underoath scored an impressive No. 2 debut, selling 97,000 copies of their latest effort, 'Define the Great Line.' That was more than enough to force the Dixie Chicks down to No. 3. Their 'Taking the Long Way' sold another 86,000 copies.

Rounding out the Top Five was another debut, this one from Keane, whose sophomore album 'Under the Iron Sea,' landed at No. 4 with 75,000 copies sold.
