Mumbai: Britney Spears’s Womanizer has claimed the No. 1 spot on Billboard’s Hot 100 Singles chart from No. 96. This is the first time a song has ever made a leap of this magnitude on the singles chart. Womanizer is also the No. 1 song on iTunes charts in Canada, France, Spain and Sweden.

The song’s astonishing climb up the charts comes despite a major glitch that occurred yesterday when the Womanizer digital track was inadvertently removed and unavailable for sale at iTunes  in the U.S. and in other countries for over a twelve hour period. The track first became available on iTunes on 7 October, and prior to the technical error, the digital track ranked No.1 there, selling over 275K units within the first six days of its release. However, the brief lapse did not slow down the momentum of the super-star’s project; currently the digital track is back up on iTunes and digital sales are expected to quickly recover.

Rounding out a record-setting week, Spears debuted her Womanizer video on ABC’s 20/20 news program this past Friday night; this is the first time a music video in its entirety  has ever premiered during primetime on ABC. Additionally, the news program won the ratings race during its time slot, coming in No.1 in the coveted 18-35 demographic. The video was directed by Joseph Kahn, who also directed Spears’ riveting Toxic video.

Womanizer is the first single from her forthcoming album, Circus and was produced by the Atlanta production team The Outsyders. For her latest album, Britney has enlisted a stellar group of established producers/writers that include Dr. Luke (who wrote and produced the album’s title track, "Circus"), Danja, Max Martin, Bloodshy & Avant and Guy Sigsworth (Madonna, Alanis Morissette, Bjork).  Her sixth studio album, Circus, is set for release 2 December, which coincides with Spears’ 27th birthday.
