"I Cry" received mixed reviews from music critics, who criticized its lyrical content and production, and stated that it would have been better with a collaboration with Sia Furler, who previously collaborated with Flo Rida on the song, "Wild Ones". However, some critics were positive towards its catchiness and club-nature. The song received commercial success upon its release, peaking inside the top ten in many countries including Australia, Austria, Canada, Denmark, Finland, France, Germany, New Zealand, Norway, Switzerland, United Kingdom and United States. A music video was released for the single on YouTube. This song is the second track on Now 45.
"I Cry" received generally mixed reviews from most music critics. Andy Gill from The Independent said that this track and "In My Mind (Part 2)" are "galloping grooves." Chris Payne from Billboard was favorable, saying, "After repeat listens "I Cry" might sound a good deal like the rest of "Wild Ones," but played in a club at the right time, it's got enough building beats and poppy climaxes to deliver."AbsolutePunk said that "I Cry" was a "decent dance cut, using a sample from the Bingo Players for the hook."
However, Melissa Maerz from Entertainment Weekly said, "Most bizarre is "I Cry", which speeds up Brenda Russell's 1988 smooth-jazz cheesefest "Piano in the Dark" until it has all the emotional heft of an LMFAO track. You couldn't program a robot to cry to it." Gleen Glomboa from Newsday said the sample of "Piano in the Dark" was "off" and wanted it to "speed up a bit." Robert Copsey from Digital Spy gave it a rather scathing review, only awarding it one star out of five. He stated, "'I Cry' is just sheer laziness [...] Flo waxes the usual lyrical nonsense about champagne buckets and his tattoo of Jimi Hendrix." Copsey also thought it would have been better as a collaboration with "Wild Ones" guest vocalist Sia Furler. He stated, "We've said it once and we'll say it again: Bring back Sia!"
