As she works on her comeback, singer Britney Spears awaits the release of her album “Circus” on Dec. 2. But fans can start delving into the album now with the release of extended segments from six “Circus” songs that were posted on Thursday at the Web site of New York radio station 103.5 KTU.

One of the songs, “Womanizer,” was already released in September, and another song “Kill The Lights” turned up on the Web site YouTube this week, then was taken down within hours and later reposted. With lyrics that include the words “Mr. Photographer, I think I’m ready for my close up tonight,” the song is a clear reference to her paparazzi-filled life. The video posted online for the song features images of Spears pole-dancing, demonstrating that Spears shows no signs of changing gears from the sex-fueled persona that helped shoot her to pop stardom.

Other songs included in the nearly 8-minute segment posted on Thursday at KTU’s Web site were: “Circus,” “Out from Under,” “If U Seek Amy” and “Unusual You.”

It remains to be seen how far the album “Circus” will propel Spears as she seeks to make a career comeback from the public meltdown she suffered in 2007 and early 2008. Since the album will be released on her birthday, the singer stands a chance to give herself an outsized present if “Circus” is a hit.
