Background and release 

Following the release of their fifth extended play 4Minute World in 2014, 4Minute took hiatus for nearly one year. On January 23, 2015, the group announced a return to music with their sixth EP, titled Crazy. Crazy yielded two lead singles. The first one, "Cold Rain", was released on January 26, 2015, through Cube Entertainment. "Crazy", the second single from the EP, was made available for digital download and streaming on February 9, 2015. The song was serviced to Korean Broadcasting System radio stations on February 10, 2015. Group member Hyuna co-wrote the song with its producers, Seo Jae-woo, Big Ssancho and Son Young-jin. Talking to Vice in 2015, Hyuna admitted that the song expressed 4Minute's true colours. Gayoon elaborated about the sonic direction:

Music and lyrics

"Crazy" is composed in the key of G major, with a fast tempo of 176 beats per minute, and runs for 3:12. Musically, "Crazy" has a more hip hop indebted sound that recalls the "urban-edginess" of the group's early tracks. It has been described as a hip hop and dance track with elements of trap. The song employs low-pitched beats, twisted horn hooks and siren-like synths in its production. "Crazy" makes use of a strong "throbbing" bassline and turbo-powered drum machines, set over snare beat twists and clapping turns. The song incorporates an instrumental breakdown that is composed of "trumpeting" synths and Middle Eastern-style flutes. Driven by heavy brass loops, the track changes direction in a "build-up-drop-down drop-off" pattern, deriving its style from EDM. The song features "sharp" rap verses from Jiyoon and Hyuna, "pulsing" vocals from Sohyun and Jihyun, and melodic belts from Gayoon, who performs on the pre-chorus. During its lyrics, 4Minute taunts the listener into the song's titular craziness and urges them to have fun.

Reception

Critical reception
"Crazy" was met with positive reviews from music critics. In his review for Vice, Jakob Dorof wrote that the song "pushes hot genres like trap and EDM harder and farther than pretty much anybody in global mainstream music."  Writing for Billboard, Jeff Benjamin praised the song for its fierce production and the group's energetic vocal performance. In another review for Fuse, Benjamin included the track as one of the 10 best dance songs of February 2015, and labelled it as "one of the biggest club bangers" of the year. Jacques Peterson of Idolator opined that 4Minute had "reinvented themselves into ferocious club kids with the relentlessly fierce 'Crazy'." He added that "it's the closest a female K-pop act has got to displaying Rihanna levels of badassery in years." Scott Interrante from PopMatters described the song as "loud and aggressive," and felt that "everything about the song, from the rapid-fire rapping" to the production and the group's "sharp choreography" translated into "crazy." Hwang Sun-up of IZM called the song's production "outstanding," which he felt blended with the imagery and concept of the track and also praised the group's vocal performance. In a separate review for Spin, Dorof listed "Crazy" as one of the K-pop highlights of 2015. He praised the song for its production and the group's performance, and dubbed the track as a "banger." In her ranking of 4Minutes' songs, music critic Tamar Herman named the track the best song of their career, labelling it as "one of the fiercest K-pop song of the decade" and lauding the song's "off-kilter composition." Billboard and Idolator listed "Crazy" as one of the best K-pop songs of 2015. The former placed it on their decade-end list of the 100 greatest K-pop songs of the 2010s at number 52, with the magazine commending the production and "the impactful delivery of the domineering raps and dynamic verses."

Music video and promotion 
In the lead-up to the release of "Crazy", the group released photo and video teasers for the track, which served as a promotional tool for their return.  An accompanying music video was uploaded to 4Minute's YouTube channel on February 9, 2015. For the visual, a choreography by Parris Goebel was commissioned, who had previously worked with Jennifer Lopez. Portrayed in black and white, the video features "moving camera-angle" shots of the group performing "non-stop" choreography while wearing sportswear and bucket hats. Discussing the choreography behind the video, Sohyun stated that it was "far more difficult to get down" as compared to their previous ones. Interrante felt that "the hair styles and fashion, along with many of the girls’ postures and poses, specifically recall American hip-hop culture, and subsequently African-American culture." Benjamin opined that the "multiple line changes" throughout the dance-routine made it "one of K-pop's top dances to watch for on the live stage." For Dorof, the video contained "some of the year's fiercest choreo[graphy]."

To promote the song and Crazy, 4Minute made appearances on several South Korean music programs around February and March 2015. They performed the song for the first time for M! Countdown on February 12, 2015, as part of their comeback stage. The following three days, the group appeared on Music Bank, Show! Music Core, and Inkigayo to perform the song.
