U2

It was a bittersweet win for U2 on the Canadian album charts this week.

The Irish rockers captured the top spot once again, despite seeing sales of their latest effort "No Line on the Horizon" drop by 67 percent.

U2's numbers reached just over 21,000, down from the 65,000 they sold last week, according to data compiled by Nielsen SoundScan.

Their entry last week achieved the best first-week sales this year to date.

Two new entries challenged U2, but ultimately fell short -- Kelly Clarkson's "All I Ever Wanted" came in at No. 2 with 14,000 in sales, and Johnny Reid's "Dance With Me" premiered at No. 3 on sales of 13,000.

The new debuts sent Lady GaGa's "The Fame," Nickelback's "Dark Horse," and Jason Mraz's "We Sing, We Dance, We Steal Things" all down two positions to No. 4, No. 5, and No. 6, respectively.

Rounding out the top 10 was Kings of Leon's "Only by the Night" at No. 7, Mario Pelchat and Michel Legrand's self-titled disc at No. 8, Dede's "A Travers Les Brumes" at No. 9, and Taylor Swift's "Fearless" at No. 10.

In the U.S., Kelly Clarkson debuted in first, followed by The-Dream's "Love vs. Money" came in second, U2 in third, the J. Holiday's "Round 2" in fourth, and Taylor Swift in fifth.
