Britney Spears tops digital download chart

"Gimme More" also shot to No. 3 on the Billboard Hot 100 singles chart, Spears' highest ranking there since her debut single, "... Baby One More Time," peaked at No. 1 in 1999. The Hot 100 is based on radio airplay, downloads and Internet streaming.

Spears' latest song was issued for digital downloads on Sept. 25 after nearly three weeks of airplay and was lodged at No. 68 on the Hot 100 chart the week before its commercial release.

Soulja Boy's "Crank That" remained at the top of the Hot 100 for the week ending Sept. 30, followed at No. 2 by the Kanye West hit "Stronger," Billboard told Reuters.
