As danceable pleas for universal understanding go, the opening track on Dangerous is shockingly tense and fragmented. The groove bears the signature sound of producer Teddy Riley, but Jackson came up with most of it. "He brought it to me as a DAT, and he told me there were things he wanted done, and I did them," Riley recalled. Jackson's voice takes its time creeping into the mix, and he stutters the chorus like his voice is being sliced to shreds; the most accessible moment of "Jam" is arguably the verse by Heavy D, Jackson's favorite rapper at the time. Unsurprisingly, the song stalled on the Pop charts but was a Top Five R&B hit.
