Singer-rapper Iyaz, otherwise known as Virgin Islands-born Keidran Jones, went straight to No. 1 on the new U.K. singles chart with his former Billboard Hot 100 No. 2 "Replay" (Reprise/Warner Music). Paolo Nutini bagged another week atop the album chart with "Sunny Side Up" (Atlantic/Warner Music).

The Iyaz single sold 106,000 copies up to Saturday night, according the Official U.K. Charts Company, a healthy total for the opening part of the sales year. That put it 9,000 units ahead of the crossover club hit that debuted at No. 2, "Riverside (Let's Go)" (Data) by Dutch DJ Sidney Samson featuring Wizard Sleeve.

"Starstrukk" (Photo Finish/Asylum/Warner Music) by 3OH!3 featuring Katy Perry climbed back 6-3 on the new chart published Jan. 10, as last week's No. 1 single, Lady Gaga's "Bad Romance" (Interscope/Universal), fell to No. 4.

Also climbing the new top ten were Florence and the Machine's cover of the club staple "You Got The Love" (Universal Island), previously a hit several times over for the Source featuring Candi Staton. That climbed 13-5, while Florence also entered at No. 23 with "Dog Days Are Over."

Journey's "Don't Stop Believin'" (Columbia/Sony Music Entertainment) continued its "X Factor"-instigated popularity with a 7-6 climb; "Look For Me" (Jive/Sony Music Entertainment) by Chipmunk featuring Taley Riley jumped 10-7 and the Saturdays' "Ego" (Fascination/Geffen/Universal) 17-9.

Other highlights of the new singles chart included a 19-12 climb for Alexandra Burke's "Broken Heels" (Syco Music/Sony Music Entertainment) and a No. 14 debut for 15-year-old Canadian discovery Justin Bieber's "One Time" (Def Jam/Universal).

Scottish singer-songwriter Nutini's second album stayed at No. 1, for the second consecutive week and third overall (including its chart-topping start last June). Florence and the Machine's debut set "Lungs" jumped 6-2 in its 27th chart week, with Lady Gaga's "The Fame" down one rung at No. 3.

The only new entry in the top 40, at No. 8, was RCA/Sony's new "Elvis 75" compilation, released to mark what would have been Elvis Presley's 75th birthday Jan. 8.
