"Shake It Off" is a song co-written by American singer Mariah Carey, Jermaine Dupri, Bryan-Michael Cox, Johnta Austin, and recorded for Carey's fourteenth album, The Emancipation of Mimi (2005). It was co-produced by Carey, Dupri and Cox. It was released as the album's third single in 2005 (see 2005 in music).
Todd Burns of Stylus magazine said that the song was "sultry". Bill Lamb of About.com said it was "little more than a pleasant piece of pop fluff [...] it is unlikely to be one of Mariah Carey's more memorable hits. Yahoo! Music's Dan Gennoe called the song "Usher-lite", a criticism shared by Sal Cinquemani of Slant Magazine: she called "Shake It Off" as "Usher by way of Dupri", and grouped it among "the songs [on the album] that don't work [...] in which Mariah too heavily bites on the styles of her successors". Blender magazine ranked it thirty-eighth on its 100 Greatest Songs of 2005 list.
The song was less successful outside the U.S. It reached the top five in New Zealand and number six in Australia, and was issued as a double A-side with "Get Your Number" in the United Kingdom and the Republic of Ireland, where it reached number nine and the top twenty, respectively.
The single's video was directed by Jake Nava and begins with Carey learning of her boyfriend's infidelity. She informs him on the PDA that she is breaking up with him, packs her bags, and leaves the apartment. Carey stops near a restaurant, and then appears in a bus speaking on her PDA, with Chris Tucker as the man in the passenger's seat. Behind the car, a sign reading "Hollyhood" comes into vision, and the video is intercut with scenes of her boyfriend accompanied by other women. Carey is then shown on bleachers at a high school baseball game. She writes "MIMI" on one of the bleachers and the letters transform into a large shiny "MIMI" sign made of lights, which Carey dances and sings in front of. In the final scene, she approaches the ocean on a beach, shaking off her dress in the process.
