"Shake It Off" is a song performed by American singer and songwriter Mariah Carey, taken from her tenth studio album, The Emancipation of Mimi (2005). It was written and produced by Carey along with Jermaine Dupri, Bryan-Michael Cox, and Johntá Austin. The song was initially solicited to radio on July 11, 2005, by Island and Mercury Records as the album's third single in the United States, while "Get Your Number" served as the album's third single elsewhere. Described by Dupri as "ghetto," the track is a R&B song that makes use of pop and hip hop influences and a simple, sparse production. Lyrically, the song follows Carey as she moves on from her relationship with an unfaithful lover, packing her things and breaking up with him over an answering machine.
