What You Maybe Didn't Know About Britney's Singles

All eyes on me.

The Britney Army has their eyes on September 17, the heavily rumored date for the lead single from Britney's next album. (A countdown on Britney's official website promises something big will happen on that day.) In anticipation of the song that will likely slay us all, here is a fun fact for each of Britney's timeless jams.

1. "...Baby One More Time" was originally written for TLC, but they rejected it. Britney fell in love with the song the minute she heard the demo, and her label lauded it as well, only requesting that "hit me" be removed from the title.
2. "Sometimes" was the subject of a lawsuit when songwriter Steve Wallace claimed he had written the song in 1990 but didn't copyright it until 2003, four years after Britney registered her own copyright for it. Emails Wallace produced in court in which Britney admitted to having stolen the song were considered fake, and Steve lost the lawsuit. #Don'tMessWithBritney
3. "(You Drive Me) Crazy" was remixed for its single release, and "The Stop! Remix" was included on the soundtrack for the 1999 film Drive Me Crazy. The film's stars, Melissa Joan Hart and Adrian Grenier, appear in the song's music video.
4. Britney recorded three versions of "Born to Make You Happy". The first contained lyrics that she deemed too inappropriate for her target audience. After the song was rewritten, Britney recorded two sets of vocals; the second were used for the official album version of the song, while the first were used as a bonus remix.
5. The music video for "From the Bottom of My Broken Heart" was meant to rehaul Britney's naughty school girl image. Her record label wanted a story-oriented and emotionally-driven clip with no choreography.
6. With a budget of $750,000 (over $1 million when adjusted for inflation), "Oops!... I Did It Again" remains one of the most expensive music videos of all time.
7. "Lucky" is frequently cited by critics as one of Britney's finest moments and is often credited with predicting her later struggles with fame.
8. "Stronger" is allegedly aimed at Britney's management and label, who were criticized by the media for micromanaging her career at the time.
9. "Don't Let Me Be the Last to Know" was written by Shania Twain. 
10. The albino Burmese python Britney danced with while flawlessly performing "I'm a Slave 4 U" at the 2001 MTV Music Awards is named Banana. Britney was reportedly terrified of the snake but went ahead with the performance anyway.
11. Though the album version of "Overprotected" was released, music video and all, Britney's label quickly commissioned a hop-hop remix and a new video, hoping it would improve the song's commercial performance.
12. "I'm Not a Girl, Not Yet a Woman" was originally recorded for the Crossroads soundtrack but used for Britney's third album instead.
13. While promoting the single release of her version of "I Love Rock 'n' Roll", Britney mistakenly attributed the song to Pat Benatar instead of Joan Jett. #awkward
14. "Anticipating" was only released in France.
15. Like "I'm a Slave 4 U", "Boys" was originally written for Janet Jackson, who is one of Britney's biggest influences. In the song, Britney sings "get nasty," which alludes to Janet's hit single "Nasty".
16. "Me Against the Music" was never intended to feature Madonna, but after Britney played a finished version of the track for her, Madonna added in her own verses.
17. "Toxic", which was originally offered to Kylie Minogue, won Britney her first Grammy.
18. Britney wrote the lyrics to "Everytime" by herself. While it is common knowledge that the song focuses on her former relationship with Justin Timberlake, Britney wrote it in direct response to his music video for "Cry Me a River", which featured a Britney lookalike, and several interviews in which Justin divulged private details of their relationship.
19. Britney suffered a knee injury on the set of the music video for "Outrageous" and had to undergo arthroscopic surgery. As a result, the video, which featured scenes with Snoop Dogg, was never completed.
20. Both Kevin Federline and Britney's brother Bryan make appearances in the music video for "My Prerogative".
21. Britney had to fight with her record label to get "Do Somethin'" released as a single.
22. Britney is the sole writer credited for "Someday (I Will Understand)", a song about feeling empowered as a pregnant woman, which she penned two weeks before learning she was expecting her first child.
23. The original version of "And Then We Kiss" was recorded for In the Zone, but it didn't make the cut. It was considered once again for the Britney & Kevin: Chaotic EP, but was left out for unknown reasons. A remixed version of the song appears on B in the Mix: The Remixes in 2005, and the original version leaked online six years later.
24. Britney initially did not want to include the line, "It's Britney, bitch," on "Gimme More".
25. Bloodyshy & Avant wrote "Piece of Me" after witnessing the singer's relationship with the paparazzi firsthand, even though they were aware of an "unwritten rule" that the label would not accept songs regarding Britney's personal life.
26. "Break the Ice" was selected as the third single from Blackout after it won 39% of votes in a fan poll.
27. "Womanizer" is Britney's best selling digital single in the United States.
28. Entire sequences of Britney walking the tight rope in the "Circus" music video were never included in the final cut.
29. "If U Seek Amy" is by far Britney's most controversial song, as a bunch of tight-ass motherfuckers couldn't handle its double entendre. As a result, the version you're most likely to hear on the radio is "If U See Amy".
30. "Radar" appears on both Blackout and Circus. Originally intended to be released as a single from Blackout, those plans were scrapped and it was released as a single from Circus in order to fulfill contractual obligations with the song's producers.
31. Britney broke hella records with "3", and at the time of the release, it was the first song in three years and first non-American Idol song in eleven years to debut at #1 on the Billboard Hot 100.
32. "Hold It Against Me" was originally written for Katy Perry, but its writers decided it was better suite for Britney.
33. "Till the World Ends" not only features Ke$ha on its remix, but was also written by the "Tik Tok" singer as well.
34. When Britney lent her vocals to the remixed version of Rihanna's "S&M", it marked the first time the singer was ever featured on another artist's song. Bitch plays hard to get!
35. "I Wanna Go" was selected as the third single off of Femme Fatale after receiving 38% of fan votes in an online poll.
36. The music video for "Criminal" stars Britney's then-boyfriend Jason Trawick.
37. "Scream & Shout" is one of three known songs recorded by Britney and will.i.am. The other two, "Big Fat Bass" and another track, were both recorded for Femme Fatale, but only the former made the cut. will.i.am is the executive producer of Britney's upcoming album, so expect more collaborations between the two.
38. Britney's management and label advised her not to record "Ooh La La" for The Smurfs 2, but she insisted because her sons were such big fans of the film.
