Alicia Keys recorded a version of "If I Were Your Woman" in which she sampled the Isaac Hayes version of "Walk On By" for her second studio album The Diary of Alicia Keys (2003). Keys sampled the same loop of Hayes' song the Notorious B.I.G. sampled on his song "Warning", which was produced by Easy Mo Bee, who co-produced Keys' version. Keys would later record a full version of the song for her first live album Unplugged (2005); it received a nomination for Best Traditional R&B Vocal Performance at the 2006 Grammy Awards.[2] Another version, entitled "If I Was Your Woman (Original Funky Demo Version)" appears on Songs in A Minor: 10th Anniversary Edition (2011).[3] Keys stated that it was "dangerous" to record the song, and commented "when I do a remake, it's not about wondering how people will criticize it. It's a private choice".[4] "If I Was Your Woman" was included on the set list of Keys' Diary Tour (2005).
"If I Was Your Woman" was generally well received by music critics in their reviews for The Diary of Alicia Keys. David Segal from The Washington Post commented that with the music from "Walk on By", the song is a "successful cross-breeding experiment".[5]Mark Anthony Neal of PopMatters felt that the song was the "funkiest and most hip-hop inflected track" on the album, adding that it "forc[ed] Keys to push towards her highest vocal register".[6]BBC Music reviewer Denise Boyd called it a "[song] to look out for" on the album.[7] Dimitri Ehrlich of Vibe praised Keys' vocal in the song, writing "Her voice is low and full, brimming with emotion. Singing as if her life depended on every note, she makes sure you feel the urgency".[8] Steve LaBate of Paste described the song as "a well-written soul-pop tune with a killer sitar hook and Keys’ chiming harp-like piano accents that eventually morph into sparse, pretty jazz chords during the verse" and concluded that it's one of the "stronger tracks" on the album.[9] Jim Farber of the New York Daily News commented that Keys took a risk by covering the song, but concluded that "she makes it her own, putting more funk in the rhythm and finding new throatiness in her voice".[10] Laura Sinagra of The Village Voice was not pleased with the song, writing that "Keys streets up Gladys Knight with "If I Was Your Woman" and might get fan points for effort, but her hip-hop "aw, aw, aw"s fail to convince".[11]
