"(You Drive Me) Crazy" is a song by American singer Britney Spears from her debut studio album, ...Baby One More Time (1999).

The song garnered positive reviews from music critics, some of whom praised its simple formula and noted similarities to Spears's debut single, "...Baby One More Time".

It features cameo appearances of actors Melissa Joan Hart and Adrian Grenier, who star in the movie Drive Me Crazy, which is named for the song.

Before recording her debut album, Spears had originally envisioned it in style of "Sheryl Crow music, but younger [and] more adult contemporary".

[2] She flew to Cheiron Studios in Stockholm, Sweden, where half of the album was recorded in May 1998,[1] with producers Max Martin, Denniz Pop and Rami Yacoub, among others.

[2] "(You Drive Me) Crazy" was written by Jörgen Elofsson, while song production and additional songwriting was done by Martin, Per Magnusson and David Kreuger.

[7] The song's composition follows a simple formula and infuses drums, guitar, and edgy synthesized instruments, including a recurring cowbell,[7][8] and having a roughly similar sound to Spears's debut single "...Baby One More Time" (1999).

Kyle Anderson for MTV considered "(You Drive Me) Crazy" as "a similar-sounding anthem [to '...Baby One More Time'] with some streamlined rock guitar taking center stage (there's even a solo).

[16] Evan Sawdey of PopMatters called it a "lightly dorky" song,[17] and Stephen Thomas Erlewine of Allmusic deemed it as a "fluffy dance-pop at its best".

[20] While reviewing ...Baby One More Time on its 20th anniversary, Billboard's Chuck Arnold felt that "sparkling with the Midas touch of Max Martin, 'Crazy' perfectly captures the crazy giddiness of young love -- the kind that keeps you up all night".

[21] The staff from Entertainment Weekly placed it at number 22 on their ranking of Spears's songs and wrote: "highlighted by her overpronunciation of "you", bell rings, and a backup choir that turns the chorus into a massive singalong.

['(You Drive Me) Crazy'] captures Spears at full force, with a robust vocal performance and an ab-emphasizing choreographed dance, remembered best through its music video".

[25] Nicholas Hautman, from Us Weekly, deemed it the singer's ninth greatest single and said: "This quasi-dorky dance track can be easily summed up using just three words: pure ear candy".

[26] For Digital Spy's Alim Kheraj the most notable thing was the song's prominent use of cowbells; "backed up by rock guitars and flawless Max Martin production, Britney sounds confident, her vocals clear and powerful".

The song peaked at number two on the European Hot 100 Singles, being held off the top spot by R. Kelly's "If I Could Turn Back the Hands of Time".

[44] Spears conceptualized the video's treatment, and explained during an interview with MTV in 1999 that "it would be cool to be in a club, and we're dorky waitresses, and we break out and start dancing.

[45] Due to Hart's appearance in the music video, parts of it were featured in the credits of the season 4 premiere of Sabrina the Teenage Witch, an episode that guest starred Spears.

Spears, now wearing a sexy, green sequined outfit, goes through the corridor to the dance floor with her friends, and starts to perform a high-profile choreography, including a chair dance sequence referencing Janet Jackson's "Miss You Much" video, which Spears also referenced in live performances of the song on the Crazy 2k Tour.

[48] Jennifer Vineyard of MTV commented, "the alternate audio gives the feel of Spears singing the song as a round, where the beat is in sync but one layer of her vocals is just slightly ahead of the other.

"[48] The music video for "(You Drive Me) Crazy" was re-created by Australian actress Rebel Wilson, in one of the scenes in the Netflix film Senior Year (2022).

[49][50] Spears performed the song for the very first time at her L'Oreal Hair Zone Mall Tour in New York City, USA on July 1, 1998.

[58] "Crazy" would not be performed by Spears for another nine years until it was included on the setlist of her Las Vegas residency show, Britney: Piece of Me (2013–2017).

[61] In the 2012 Glee episode "Britney 2.0", the characters of Marley Rose and Jake Puckerman performed a medley of the track with Aerosmith's "Crazy" (1993).
