Background and composition "What You Don't Know" features a prominent horn section accompanying the singers, and there is a guitar solo between the second and third verses. Although the group continued to have success on the dance charts, this was one of the final Exposé pop hits featuring a beat, with which they had become associated from most of the singles off their previous album, Exposure (1987). Many of the singles released by the group from this point on were mid-tempo or ballads.
Music video The accompanying music video for "What You Don't Know" features the singers rehearsing with a band on stage, then near the end of the music video the girls rush back to be with their respective boyfriends.
