<P> Mendler co-wrote the song with Emanuel Kiriakou, Evan Kidd Bogart and Andrew Goldstein . Thom Bell and William Hart are also credited as co-writers, because the song's chorus loosely interpolates the 1968 Delfonics song "Ready or Not Here I Come (Can't Hide from Love)", which they wrote . That song had also been interpolated in the chorus of the 1996 song "Ready or Not" by The Fugees . </P> <P> The track was produced by Kiriakou and Goldstein . </P> <P> The song is an up - tempo pop track with a strong undercurrent of soul . A Popdust review stated that "every detail is where it should be, from the multi-tracked vocals on the chorus to the synth sound effects that provide punctuation and punchlines to the verses, to some of the more clever rhymes in the lyrics--which include pairing "Oprah" with "Boca" and "I'm like a crook tonight" with "I could be your kryptonite ." The song consists of "layers of synths and backing vocals adding a musical and emotional intensity totally absent from the carefree verses ." The song also mentions Prince William and Kate Middleton . Mendler's vocals span from the low note of A to the high note of Eb . </P> <P> The song received praise from music critics . Andrew Unterberger of Popdust was very positive with his review, saying that the song "is a playful, swinging and just impossibly catchy--the catchiest we've heard since our girl Carly Rae--pop number". He also praised Mendler's vocals and chorus . He concluded his review saying that "Will that out - of - placeness hurt the chances of (Ready or Not) becoming the smash it deserves to be, though? Well, it didn't seem to hurt "Want U Back" any, so we're hoping that people can see that this song is basically a smarter, more interesting and infinitely catchier version of that already - quite - good Cher Lloyd song . But it's on all of us to spread the world that that song scraping the bottom of the iTunes chart isn't just another kiddie - pop anthem from the latest made - for - Disney movie--it's one of the best songs of the year, and one you'd have to be a pretty sullen sort of person to not love at least a little bit ." Devin Alessio of Seventeen said that "(Mendler) is in line to be the next superstar off the Disney Channel". She praised her vocals, saying that "her sound is a mix between Carly Rae Jepsen and Demi Lovato" and described the music video as "super fun". She concluded that "(Ready or Not) is a total girl anthem--perfect for listening to when you're just chilling with your friends or getting ready for homecoming ." </P>
