In the "Billboard" magazine review of the album, contributor Katy Kroll wrote that Timberlake "claims to be bringing 'sexy' back to pop music, and indeed he is. You can almost feel beads of sweat rolling off the title track and 'SexyBack' featuring Timbaland". Chris Willman of "Entertainment Weekly" was complimentary towards Timbaland, producer of the song, writing that Timbaland offers "tougher, trickier rhythms, minimal live playing, a plethora of hip-hop cameos, and a self-consciously hard, edgy club sensibility" to "SexyBack". Russell Baillie of "The New Zealand Herald" noted, "The producer's angular synthesizer crunch is all over it – at best on the single 'SexyBack' where they dispense with a chorus, leaving the song sustained by its vocal fireworks, electrofunk and Timberlake's repeated declaration that 'I'm bringing sexy back. PopMatters' contributor Quentin B. Huff wrote that "SexyBack" was the "fraternal twin" to Nelly Furtado's 2006 song "Promiscuous". Andrew Murfett of "The Age" wrote that the song was a "raunchy club banger that slyly suppresses" Timberlake's customary falsetto. He continues, "it's introduced a new phrase into the pop cultural lexicon". Glenn Gamboa of "Newsday" was complimentary towards the song, writing that it was "Timberlake at his best, mainstreaming a combination of the wild, edgy dance-pop style of Basement Jaxx with Missy Elliott's more experimental hip-hop to create a boldly inventive sound that still pleases the masses."
