to Micha Frazer-Carroll from The Independent, One in a Million "had a bold, expansive vision, with tracks effortlessly bouncing from trip-hop to sensual slow jams to jungle beats". The album opens with an "alarm call" from the jungle-inspired intro "Beats 4 Da Streets", featuring commentary from Missy Elliott. Throughout the intro, Elliott repeatedly calls Aaliyah's name and tells her to wake up, while various sounds such as echoing amid bells, blippy synths, and heavy bass are playing in the background. The second track "Hot Like Fire" is a "fine" trip hop song and it is described as a "panting minimalist controlled-blaze baby-maker" with suggestive lyrics. On "Hot Like Fire", Aaliyah "hums and moans promises to her new bae that his patience will be rewarded". The album's title track is an ethereal club ballad with "seductive" trip hop, funk, electronica, and drum and bass influences; it features "shimmering" synths and crickets within its production. On "One in a Million", Aaliyah "communicates love and commitment to her man." The fourth track "A Girl Like You" is a hip hop-inspired track with a "standard 90s boom-bap beat", where Aaliyah "holds her own" against featured rapper Treach from Naughty by Nature. During the chorus, both Aaliyah and Treach engage in a "cute back-and-forth". The fifth track "If Your Girl Only Knew" is a "bouncing" funk, pop and hip hop song described by critics as "teasingly witchy".

The sixth and seventh tracks "Choosey Lover (Old School/New School)" and "Got to Give It Up" are both covers, of songs originally performed by The Isley Brothers and Marvin Gaye, respectively, with the latter featuring a guest appearance from rapper Slick Rick. "Choosey Lover (Old School/New School)", "mimics the 1983 original faithfully for the first four minutes before departing into a more modern extended outro". While, on "Got to Give It Up", Aaliyah places her falsetto "toe to toe against the liquid overlapping rhyme scheme of hip hop's ultimate storyteller Slick Rick". On the eighth track "4 Page Letter", Aaliyah tells her "crush to keep an eye out for the mailman" because she has sent him a love letter, while recalling and following her parents' advice. The ninth track "Everything's Gonna Be
