B runo Mars' "Doo-Wops & Hooligans" celebrated a year on the U.K. album chart yesterday (Jan. 15) by going back to where it started, at No. 1. Multiple BRIT Award nominee Jessie J is celebrating her second chart-topping single in the market after "Domino," also currently her first top 20 success on the Billboard Hot 100, climbed 8-1.

Mars' album debuted at the album chart summit a year ago, falling to No. 2 in its second week, but has never dropped lower than No. 14 in its entire sales year. It now has total U.K. sales of 1.28 million copies, according to the Official Charts Company, but sold a mere 24,000 new units last week to go back to the top. Last week's No. 1, Adele's "21," fell to runner-up spot as another star of last week's BRIT Award nominations, Ed Sheeran, held at No. 3 with "+".

Londo rock band the Maccabees, whose third album "Given To The Wild" had topped the midweek sales flashes, landed at No.  4 on the official week-end chart. That's still a career-best ranking, after "Colour It In" reached No. 24 in 2007 and "Wall of Arms" No. 13 in 2009.

In a further sign that rock music is staging a comeback after last year's chart domination by female artists, three more titles returned to the top ten, all by artists with new BRIT Award nominations. The Vaccines' "What Did You Expect From The Vaccines" climbed 16-6, having debuted at No. 4 last March; "Noel Gallagher's High Flying Birds" rebounded 14-8, three months after opening at No. 1; and another Columbia rock heavyweight, Kasabian, moved back 17-9 with "Velociraptor," which had a week at No. 1 at the end of September. There's still no moving "Now! That's What I Call Music 80" on the compilation chart, which it tops for an eighth week.

Jessie J narrowly missed the No. 1 spot with her debut U.K. hit "Do It Like A Dude," which peaked at No. 2 in this week last year. But she then had two weeks at the summit last February with "Price Tag," featuring B.O.B., and now visits the rarified atmosphere again with "Domino," on sales of 57,000 units. It's the fifth U.K. top ten single from "Who You Are," which fell 8-12 on the new album chart.

Last week's No. 1 single, Flo Rida's "Good Feeling," dipped to No. 2, as hip-hop duo Rizzle Kicks climbed again 5-3 with "Mama Do The Hump." "Dedication To My Ex (Miss That)" by Lloyd featuring Andre 3000 and Lil Wayne also improved again, 10-5, while "Titanium" by David Guetta featuring Sia raced 61-8, having spent two weeks in the top 40 last August, peaking at No. 16. Beyoncé's "Love On Top" jumped 20-13 and Pixie Lott's "Kiss The Stars" made its top 75 debut at No. 14.
