Oops!... I Did It Again is the second studio album by American singer Britney Spears. It was released on May 3, 2000, by Jive Records. Following the enormous commercial success of her debut studio album ...Baby One More Time (1999) and the completion of its accompanying concert tour of the same title, Spears began recording material for her second studio album in September 1999. Pressured to duplicate the success of ...Baby One More Time, she collaborated with a wide range of producers, including Max Martin, Rami Yacoub, Per Magnusson, David Kreuger, Kristian Lundin, Jake Schulze, Darkchild, and Robert John "Mutt" Lange for Oops!... I Did It Again. The final result was a pop, dance-pop and teen pop record exceedingly in the vein of ...Baby One More Time, but incorporating funk and R&B. The production, sonic quality, and Spears's vocal performance received critical acclaim upon the album's release.

Oops!... I Did It Again was a massive commercial success worldwide, debuting at number one in over 20 countries. In the United States, the album debuted at number one on the Billboard 200, with first-week sales of 1.319 million copies, holding the record for the fastest-selling album by a female artist and the largest first-week sales for a female album for 15 years, until being surpassed by Adele's 25 (2015), which sold over 3.38 million copies in its first week. In addition, Oops!... I Did It Again received a nomination for Best Pop Vocal Album at the 43rd Annual Grammy Awards (2001). It became Spears's second consecutive album to be certified diamond by the Recording Industry Association of America (RIAA), making Spears the youngest artist to have multiple diamond albums. With worldwide sales of over 20 million copies, it is one of the best-selling albums of all time.

Oops!... I Did It Again produced four singles. The title track was a global commercial success, reaching number one in 17 countries and peaking at number nine on the US Billboard Hot 100. "Lucky" peaked within the top ten in 16 countries, but only at number 23 on the US Billboard Hot 100. "Stronger" peaked at number 11 on the US Billboard Hot 100. The final single "Don't Let Me Be the Last to Know" was moderately successful across Europe but did not chart in the United States. To promote the album, Spears performed on several television shows and award ceremonies, including a controversial performance at the 2000 MTV Video Music Awards, also hosting and performing for the first time on Saturday Night Live. Furthermore, she embarked on her third concert tour, entitled the Oops!... I Did It Again Tour (2000). On May 16, 2025, the 25th anniversary edition of the album was released.

Recording and production

After vacationing for six days following the completion of the ...Baby One More Time Tour in September 1999, Spears returned to New York City on September 20 to begin recording songs for her second studio album. Producers Max Martin, Eric Foster White, Diane Warren, Robert Lange, Steve Lunt, and Babyface made contributions to the album. "Where Are You Now" and bonus track "You Got It All"–a cover of the Jets' 1986 song of the same title–were outtakes from the recording sessions for ...Baby One More Time. The songs "Oops!... I Did It Again", "Walk on By", "What U See (Is What U Get)", and "Don't Go Knockin' on My Door" were recorded at Martin's Cheiron Studios within the first week of November. Spears recorded "Don't Let Me Be the Last to Know" at Lange's villa in Switzerland in December 1999; Lange produced the song. "Stronger" and "Lucky" soon followed, and were finalized along with the title track in January 2000.

By January, the then-untitled Oops!... I Did It Again was halfway to completion. Instrumental tracks and melodies of "Girl in the Mirror" and "Can't Make You Love Me" had been recorded in the fall of 1999 in Sweden, with Spears recording the vocals on January 14 at the Parc Studios in Orlando, Florida. After recording internationally, Spears returned to New York City, linking up with producer Steve Lunt to record Diane Warren's "When Your Eyes Say It" at the Battery Studios on January 28, which preceded her Total Request Live appearance that day. "One Kiss from You" was also recorded at the Battery Studios, later being finished at 3rd Floor in New York City. Spears also demoed and recorded "Dear Diary", which would later be completed at East Bay Recording in Tarrytown, New York and at the Avatar Studios in New York City. Spears' cover of "(I Can't Get No) Satisfaction" was recorded with Rodney Jerkins at the Pacifique Recording Studios in Los Angeles during February 24–26, 2000, after the 42nd Annual Grammy Awards.

Spears was heavily pressured to repeat the tremendous commercial success of ...Baby One More Time, stating: "It's kind of hard following ten million, I have to say. But after listening to the new material and recording it, I'm really confident with it." Upon the album's release, Spears said: "I mean, of course there's some pressure", and added: "But in my opinion, [Oops!] is a lot better than the first album. It's edgier – it has more of an attitude. It's more me, and I think teenagers will relate to it more." Geoff Mayfield, director of the Billboard charts, added that the decision to release Oops!... I Did It Again less than a year and a half after Spears' debut amounts to "very smart timing. My philosophy is when you have a young fan base, get 'em while they're hot."

Music and lyrics Oops!... I Did It Again was considered the sequel to ...Baby One More Time, percolating with a carefully measured blend of pop, funk, R&B and power balladry. Spears said in an interview that the album showcased a more mature, R&B-flavored pop sound. "It's not something I changed purposefully", Spears said of the album's sound and added: "It's just something that kind of changed on itself with me being older. My voice has changed a little bit and I'm more confident, and I think that comes across on the material." Rodney "Darkchild" Jerkins talked about working with Spears on the cover of the Rolling Stones' "(I Can't Get No) Satisfaction", stating: "It's going to shock everybody. It has flavors of the original, but it's a straight 2000 version — new to the ear. Which I think is cool, because people who appreciate that song are going to love it. And I made it so new and young that the young kids that love Britney are going to love it. It's going to grab both a mature and young audience." Spears worked with Robert "Mutt" Lange on "Don't Let Me Be the Last to Know", telling MTV News: "When you hear the song, it's so pure and delicate. It's just one of those songs that pull you in", and added: "I think they wrote it 'specially for me, because the lyrics of the song, if you really listen … they're more of what I can relate to, 'cause they're kind of young lyrics, I think. I don't think Shania would probably sing some of the words that I'm saying."

Oops!... I Did It Again opens with its title track, which was compared to her debut single, "...Baby One More Time" (1998), featuring a slap-and-pop bassline, synthesizer chord stabs and a mechanized beat. Lyrically, the song sees Spears warning to an overeager prospective lover: "Oops, you think I'm in love / That I'm sent from above / I'm not that innocent." The song also breaks down for a spoken-word interlude, involving a line referencing the film Titanic (1997). The second track "Stronger" is a synthpop and R&B-infused track, which is lyrically a declaration of independence, seeing Spears leaving a partner who treats her as property. The line "my loneliness ain't killing me no more" makes reference to the verse "my loneliness is killing me" from her debut single "...Baby One More Time". Another R&B-infused track which also incorporates funk, "Don't Go Knocking on My Door" finds Spears confidently forging ahead after a breakup. "(I Can't Get No) Satisfaction" begins with mushy guitar plucking and breathy coos, until a dry, crackling lockstep is thrown down, turning the song into an urban stomp. The dance-pop cover also jettisons the song's final verse and adds new lyrics (i.e. "how white my shirts could be" becomes "how tight my skirt should be"). "[It] was my idea [to record the song]", Spears said, adding: "I was just like, 'I like this song,' and I think it will be a really cool combination working with [Jerkins] and doing a really funky song like that."

The fifth track "Don't Let Me Be the Last to Know" was co-written by country pop singer-songwriter Shania Twain and her then-husband Lange, who also produced the track. The ballad, which boasts a slinky keyboard riff and Lange's characteristically lavish production, finds Spears allowing a bit of "country twang" into her vocals as she begs a lover to reveal his feelings: "My friends say you're into me ... but I need to hear it straight from you". "What U See (Is What U Get)" demands respect by rebuking a jealous partner, while "Lucky" is a heart-rending tale of a Hollywood starlet's loneliness, proving that fame can be empty: "If there's nothing missing in my life/Then why do these tears come at night?". "School crush" is the lyrical theme of "One Kiss from You", a track with a reggae-style beat and lyrics about the feelings of falling in love and the quickness of it, with Spears cooing that after only one kiss she sees her entire future with her lover. The ballad "Where Are You Now" talks about wanting to know where a former lover is and what they have been up to, so that the protagonist can finally let them go and find closure. Lines on the Europop track "Can't Make You Love Me" state that fancy cars and money pale in comparison to true love, with Spears singing: "I'm just a girl with a crush on you." The mid-tempo, synth-backed "When Your Eyes Say It", written by songwriter Diane Warren, combines a string section with a loping hip hop beat, while Spears makes her own songwriting debut on the modest, keyboard-driven ballad "Dear Diary", which she said was autobiographical. On the track, she sings about wanting to become "so much more than friends" with a boy.
