Till the World Ends

"Till the World Ends" was written and produced by Dr. Luke and Max Martin, with additional writing by American recording artist Kesha and Alexander Kronlund, and additional production by Billboard. In an interview for Spin on February 11, 2011, Kesha announced she had co-written the song with Luke and Martin for Spears's then-upcoming album Femme Fatale, explaining it was inspired by "me imagining [Spears] and any female musician touring the world. When you go out, and you're having an amazing, magical night and you don't want to go to sleep and you want it to last until the world ends."{{cite web|url =https://www.spin.com/2011/02/keha-talks-u-tour-its-epic-dance-party/|title =Ke$ha talks US Tour: 'It's an Epic Dance Party'|work =Spin|publisher =Spin Media LLC|last =O'Donnell|first =Kevin|date =February 11, 2011|access-date =March 3, 2011|archive-date =May 6, 2015|archive-url =https://web.archive.org/web/20150506155237/http://www.spin.com/2011/02/keha-talks-u-tour-its-epic-dance-party/|url-status =live}} She further elaborated for Vulture:

"I've never been more proud of anything in my career... It really solidifies me as a songwriter in the pop music world, which is what I consider myself first and foremost. So it actually is really, really exciting for me when I hear [Britney] sing it. Like, when I hear my own songs on the radio I have to kind of turn it down or change the radio or whatever. When I hear that, I fucking blow the speakers out and I order everybody to dance."{{cite web|url=http://nymag.com/daily/entertainment/2011/06/keha_explains_why_she_gave_suc.html|title=Ke$ha Tells Vulture Why She Gave a Hit Song Away to Britney Spears|work=New York |last=Marcus|first=Bennett|date=June 15, 2011|access-date=September 24, 2011|archive-date=September 15, 2011|archive-url=https://web.archive.org/web/20110915072911/http://nymag.com/daily/entertainment/2011/06/keha_explains_why_she_gave_suc.html|url-status=live}}

"Till the World Ends" is an uptempo dance-pop and electropop song, with an electro beat and elements of trance and Eurodance. The song opens with sirens and a "sizzling" bassline.{{cite web|url=http://music.aol.com/blog/2011/03/04/britney-spears-leaks-second-single-till-the-world-ends-a/|title=Britney Spears Leaks Kesha-Penned Single 'Till The World Ends' and 'Femme Fatale' Tracklist|last=Benitez-Eves|first=Tina|date=March 4, 2011|access-date=March 4, 2011|publisher=AOL|archive-url=https://web.archive.org/web/20110313005508/http://music.aol.com/blog/2011/03/04/britney-spears-leaks-second-single-till-the-world-ends-a/|archive-date=March 13, 2011|url-status=dead}}{{cite web|url=http://www.digitalspy.co.uk/music/singlesreviews/a307205/britney-spears-till-the-world-ends.html|title=Britney Spears: 'Till The World Ends'|last=Copsey|first=Robert|date=March 4, 2011|access-date=March 4, 2011|publisher=Digital Spy.

The melody's 4:3 cross-rhythm continues into a chant-like segment, in which "whoa-oh-oh-oh" is repeated. The bit was compared by Scott Shettler of AOL to the "rapid word repetition" of Kesha. Keith Caulfield of Billboard said the chorus "comes on hard like it's the sexy spawn" of American recording artist Usher's "OMG" (2010) and Italian band Baltimora's "Tarzan Boy" (1985).

Gerrick Kennedy of the Los Angeles Times stated that like her previous single "Hold It Against Me", "Spears's main intention with her new single seems to be keeping the dance floor pulsating with sweaty bodies". Jason Lipshutz of Billboard said the song recalls past hits by English recording artist Taio Cruz, Swedish recording artist Robyn and Spanish recording artist Enrique Iglesias. Allison Stewart of The Washington Post felt the song was comparable to Iglesias' "Tonight (I'm Lovin' You)" (2010). Sal Cinquemani of Slant Magazine and a reviewer from Popjustice compared it to Kesha's "Blow" (2011). According to the sheet music published at Musicnotes.com by Kobalt Music Publishing Inc., "Till the World Ends" is set in the simple quadruple meter time signature, with a moderate dance beat infused metronome of 132 beats per minute.{{cite web|title=Digital Sheet Music – Britney Spears – Till the World Ends|last1=Kronlund|first1=Alexander|last2=Sebert|first2=Kesha|last3=Gottwald|first3=Lukasz|last4=Martin|first4=Max|publisher=Musicnotes.com.

Lyrically, the song talks about dancing until the end of the world.

Rolling Stone named "Till the World Ends" as the third best song of 2011.

"'Till the World Ends' was already the best Britney single since 'Toxic', an ecstatic Euroclub floor-filler about wanting to dance until the world ends and other important matters. Then they added the Nicki Minaj verse. In her 45-second evisceration, Nicki manages to squeeze in chicken noises and the words 'poultry', 'Epsom salt', and 'Ricki Lake'-- not to mention the immortal diss 'Sniff, sniff, criiiies/ I done slayed your entire fucking liiiiife.' (Fact: In 2011, pretty much any song in the world could be made infinitely better by the addition of a Nicki Minaj verse.) Sprinkle a little bit of Kesha, the song's co-writer, on the chorus, and you've got a three-headed diva Hydra that sums up the recent changing of the femme pop guard from airbrushed and perfect to (relatively) weird and chaotic. It's the year's greatest quickie cash-in remix created to boost the chart position of a floundering single. Considering the ubiquity of the practice, that's saying something."{{cite web|url=http://pitchfork.com/features/staff-lists/8726-the-top-100-tracks-of-2011/3/|title=The Top 100 Tracks of 2011|last=Philips|first=Amy|date=December 12, 2011|access-date=December 15, 2011|work=Pitchfork Media|archive-date=January 7, 2012|archive-url=https://web.archive.org/web/20120107160251/http://www.pitchfork.com/features/staff-lists/8726-the-top-100-tracks-of-2011/3/|url-status=live}}

A Bollywood version of the song was done by Indian music producer duo Salim and Sulaiman Merchant, and released on DesiHits.com, a website for South Asian music and entertainment news. The remix features a Punjabi breakdown with South Asian sounding vocals and includes some added Desi flavors courtesy of dholki, dhol and tumbi beats, which are common instruments in South Asian music. Baba Kahn of the production team Culture Shock stated, "Our goal was to take Britney's smash hit single and give fans a total Desi adrenaline rush. The result is a Culture Shock musical Desi roller coaster that hopefully everyone around the world will want to join." Mark Flaherty, senior vice president of Jive Label Group, said about the remix:{{cite web|url=http://www.mtv.com/news/articles/1662227/britney-spears-till-the-world-ends-bollywood-remix.jhtml|title=Britney Spears 'Till The World Ends' Bollywood Remix Hits Web|last=Vena|first=Jocelyn|date=April 19, 2011|access-date=May 22, 2011|publisher=MTV.

"We wanted to build an even greater connection between the world's biggest pop star and one of the world's largest audiences. Britney has been engaged with South Asian culture for many years.

In the special, Spears is seen watching the playback, as she later explained, "[It is] just to make sure it's right and that the costume looks right and the dancers are together and we all look in unison. It's an energy and it looks fresh. It has a certain vibe with it and it makes sense." She also went on to describe the set as "grimy and gross [...] It was sweat and it was disgusting sometimes". At a point in the shoot, Spears changed her heels to Ugg boots during the shots that did not show her feet, stating that "[Dancing in heels] hurts ... but it looks good. It wasn't a full-length shot, so a girl's about comfort when it's not showing." Spears said that she did not feel the need to top herself, saying that "I've made so many videos that I'm at the point that I genuinely want to enjoy myself, and I have such a good team of people with me. [...] I had never worked with Ray Kay before. I was really happy with the work we did." The video was choreographed by Brian Friedman. On April 4, 2011, it was announced that two different versions of the music video would be released, a director's cut and a choreography cut. The same day, Spears tweeted a 30-second preview of the video, announcing, "#TillTheWorldEnds video premieres THIS Wednesday on VEVO. Cant wait to share it with you guys!"

The video begins with the words "December 21st, 2012" flashing on screen, the day that refers to the fulfillment of the Great Cycle, Baktun in the Mayan calendar. Spears appears strutting in an underground party wearing a studded leather jacket and stockings. Several people are seen running to a manhole and enter the sewer system to arrive to the party. This is followed by a dance routine in which Spears is wearing a sequined bodysuit and a small jacket with shoulder pads accompanied by female dancers. During the video, there are scenes of buildings burning and debris falling, as well as intercut scenes of Spears in front of an illuminated background. As the second verse begins, she dances provocatively with her male dancers. In the last chorus, the sun rises while water is sprayed through the dance floor and the earthquake and meteor shower subside. The video ends with Spears coming out of a manhole wearing the red bodysuit and smiling.

The director's cut premiered on April 6, 2011, at 03:00 EST (08:00 UTC).{{cite web|url=http://www.mtv.com/news/articles/1661302/britney-spears-til-the-world-ends-video.jhtml|title=Britney Spears Drops 30-Second 'Till The World Ends' Video Preview|last1=Byrne|first1=Katie|last2=Vena|first2=Jocelyn|date=April 4, 2011|access-date=April 6, 2011|publisher=MTV.

The video is similar to the director's cut, but has a few differences. The choreography cut offers lengthier shots of Spears and her dancers, and much of the apocalypse storyline is edited out. The clip's ending is also different from the original: instead of emerging from the manhole Spears just looks into the camera, apparently still hiding in the underground party and hinting at a darker ending in which the world does end.{{cite web|url=http://www.mtv.com/news/articles/1662033/britney-spears-till-the-world-ends-music-video.jhtml|title=New Britney Spears 'Till The World Ends' Video Hits Web|last=Vena|first=Jocelyn|date=April 15, 2011|access-date=April 18, 2011|publisher=MTV.

Once Spears enters the room and starts playing Twister with the girls, the scenario changes to a stage with a colorful background, and they all start performing a dance routine to a remix of the song. After the song stops and the four girls are seen laying down tired, Spears turns around to them and say, "Way to rock the spots, ladies."

Spears first performed "Till the World Ends" at Rain Nightclub in the Palms Casino Resort on March 25, 2011. After performances of "Hold It Against Me" and "Big Fat Bass", Spears appeared wearing a black latex bodysuit covered in red lights and surrounded by her dancers, while the stage was filled with ladders and LED lighting. At the end, she ascended the ladders and ended up on a platform, gyrating from above the room. As fireworks lit the stage, Spears danced and tossed her hair as the song closed.{{cite web|url=http://www.mtv.com/news/articles/1660729/britney-spears-las-vegas-performance.jhtml|title=Britney Spears Electrifies Las Vegas With Nightclub Performance|last=Vena|first=Jocelyn|date=February 25, 2011|publisher=MTV.

Spears emerged onstage for the chorus and performed alongside Minaj and her back up dancers while walking to a minor stage.{{cite magazine|url=http://www.billboard.com/articles/news/471534/britney-spears-joins-rihanna-nicki-minaj-performances-at-2011-billboard-music|title=Britney Spears Joins Rihanna, Nicki Minaj Performances at 2011 Billboard Music Awards|last=Herrera|first=Monica|date=May 22, 2011|access-date=May 22, 2011|magazine=Billboard|archive-date=March 29, 2013|archive-url=https://web.archive.org/web/20130329115425/http://www.billboard.com/articles/news/471534/britney-spears-joins-rihanna-nicki-minaj-performances-at-2011-billboard-music|url-status=live}}

Spears also performed "Till the World Ends" at the Femme Fatale Tour (2011). At the end of "Toxic", she goes below the stage and returns wearing a black sparkly bodysuit for "Till the World Ends". Halfway through the performance, Minaj appears on the backdrops rapping her verse of the Femme Fatale Remix of the song. She also joined Spears to perform the verse in select cities. After the song changes back to the original version, Spears starts flying in a platform with giant angel wings. The show ends with Spears and her dancers thanking the audience, as confetti falls and the "Femme Fatale" sign is lowered onstage.{{cite magazine|url=https://www.rollingstone.com/music/news/britney-spears-proves-shes-still-got-it-at-femme-fatale-tour-kickoff-20110617|title=Britney Spears Proves She's Still Got It at 'Femme Fatale' Tour Kickoff|magazine=Rolling Stone|last=Walters|first=Barry|date=June 17, 2011|access-date=June 17, 2011|archive-date=June 27, 2012|archive-url=https://web.archive.org/web/20120627185501/http://www.rollingstone.com/music/news/britney-spears-proves-shes-still-got-it-at-femme-fatale-tour-kickoff-20110617|url-status=live}} Jason L.
