– A7 – Bm7 and A/C♯. The Pussycat Dolls' vocals on the song span F♯3 – E5. Lead singer Nicole Scherzinger was noted for using the "thin end of [her] alto-into-soprano register". A pop song with soul influences, "Stickwitu" features strings accompanied by bass, harmonica, organ, piano, and the Rhodes piano. Kalefah Sanneh of The New York Times found the melody to be simple, adding that "the beat keeps dropping out and returning and growing and shrinking, confounding expectations". Chuck Taylor of Billboard noted that "Stickwitu" is reminiscent of the works of fellow girl groups Cover Girls and Sweet Sensation, while Tony Heywood from musicOMH compared the song to the works of the Spice Girls. An ode to monogamous relationships, the Pussycat Dolls croon during the chorus, "Nobody gonna love me better / I'ma stickwitu forever". Release In July 2005, MTV News reported that "Beep", featuring will.i.am, was a "potential second single". However, on September 26, 2005, A&M Records and Interscope Records serviced "Stickwitu" to contemporary hit radio stations as the second single from PCD. Jeff Leeds of The New York Times noted that the release of the single coincided with the label strucking a deal with the toymaker Hasbro to create a line of dolls modeled after the group. The aim of "Stickwitu" was to appeal to a wider and younger demographic, managing to receive airplay on outlets such as Radio Disney. In response to the release of the single, Scherzinger felt it was a strong move for them, as opposed to coming out with "Beep", noting: "occasionally we get the skeptical people, but we go, 'Give us a chance'." An urban remix featuring singer Avant was released in December 2005. The remix has identical credits to the original "Stickwitu", with the addition of Avant as a songwriter and Peter Mokran as a remixer. Scherzinger recorded new vocals with Avant in a similar way Avant sang with Keke Wyatt on "My First Love". The remix was included on the tour edition (2006) of PCD and on Avant's fourth studio album Director (2006). Critical reception Jim Carroll of the Irish Times wrote that "Stickwitu" is "one of the best pop ballads of recent years". Taylor was surprised of "Stickwitu"'s release following "Don't Cha" and praised for being "beautifully sung, craftily produced and refreshingly gimmick-free". He continued praising the "catchy" chorus noting the "track is unlike anything else on the air".
