Pop punk quartet Fall Out Boy have secured the No. 1 slot atop the Billboard charts with Infinity on High, the band's fourth full-length, which sold 260,000 copies in its debut week, Billboard.com reports. In addition, the band's single "This Ain't a Scene, It's an Arms Race" has placed No. 2 on the Billboard Hot 100. British indie rockers Bloc Party have notched a personal chart record by nabbing the No. 12 spot with 48,000 copies of their sophomore album, Weekend in the City, sold its first week out. Bloc Party's debut album Silent Alarm crested at No. 114 in 2005.

Elsewhere on the charts, Justin Timberlake's FutureSex/LoveSounds has climbed 6 places to the No. 10 slot, British songstress Corinne Bailey Rae's self-titled debut jumped from No. 17 to No. 9, and Norah Jones' Not Too Late, which appeared at No. 1 last week, dropped one place.
