Spears' upcoming album, Circus, was briefly posted on a radio station's Web site before being removed. The snippet of disco-inflected track, called "Womanizer," was briefly posted on the Web site of Nashville radio station 107.5-FM The River before being taken down, although at press time the clip could still be found elsewhere online.Based on the brief snippet, the Outsyders-produced song is a bouncy dance track with a sing-song chorus that frequently repeats the title; Britney coos about a possible lover who has a reputation of being a womanizer.

According to Britney's label, the station obtained the snippet by recording a phone call in which a radio rep played a rough mix of the song for people at the station — which seems likely, judging by the horrendous sound quality of the clip. At the label's request, the station removed the clip from its Web site.

Fans won't have to wait long for the song's official release, which takes place on Monday. The album follows on December 2, Britney's birthday.

Along with the Outsyders, collaborators on the album include Keri Hilson, Sean Garrett, Rodney Jerkins, Lil Jon, Nate "Danjahandz" Hills (who helmed "Gimme More and Dr. Luke (who wrote and produced the album's title track), Guy Sigsworth, Bloodshy & Avant (who produced past hits "Toxic" and the big VMA winner "Piece of Me") and Max Martin (who wrote "... Baby One More Time" and "Oops! ... I Did It Again").
