Circus (Britney Spears album) "Circus" marked the longest time she had spent recording an album, adding, "I think it is more urban [...] I'm writing every day, right here at the piano in this living room" and also described the album as her best work to date. Producer Claude Kelly discussed the album's initial lack of concept saying, "When I went in with [Dr. Luke] we knew we were going to maybe write something for [Britney], but there was no concept, it was just knowing her style and knowing what she does. Max Martin, who produced Spears' debut single "...Baby One More Time", produced
Britney Spears: In the Zone "Britney Spears: In the Zone" but was omitted. Spears later considered including a new version of the song featuring vocals from rapper AC on her fifth studio album "Blackout" (2007), with a review of the song from "DJ Booth" saying: "On a possible inclusion to her yet-to-be-titled comeback album (dropping this November), Spears has hooked up with producer Tricky Stewart for the song "Sippin' On". The mid-tempo track has the same familiar drum pattern as Nas' "I Can"; except here lyricism has been replaced by sexiness. After all, come the end of the song Britney does a 'soul clap'." Other
