Kellman called "Dip It Low" the biggest highlight of the album, but said that despite the album's "handful of bright spots", Milian "will need to be more convincing during the ballads next time out in order to be considered a true force." Kelefa Sanneh of The New York Times said that although "Dip It Low" was one of the summer's most popular songs, the album included an even better song, "I Need More". Sanneh explained that Milian "breathes a serpentine melody over a beat that consists of jagged snippets: some guitar chugging, a few handclaps, a couple of strategically placed beeps and, in the chorus, an unexpected nose-diving bass line." Contrary to the views of other critics, Barry Walters of Rolling Stone said that although the ballads were "gooey", "the love songs work better than the dance tracks". Etta James of People believed that Milian struggled to find her own musical identity on the "fun but formulaic CD". James praised the "sexy booty bumper" "Dip It Low" for its "reggae-ish bass groove, a hypnotic Middle Eastern refrain", and called Fabolous' rap "perfectly chilled". The reviewer thought "Highway", the album's "most erotically charged track", sounded like a female answer to R. Kelly's "Ignition". While James found the album's most personal song, "Oh Daddy", to be the unsuccessful, she said that at least "it gives us a glimpse into the real Christina".
