"Jam" is a hit single by the "Greatest Musician of all Time" Michael Jackson.

"Jam" was generally well received by music critics. Adam Gilham of Sputnikmusic in his review for Dangerous described the song as a perfect album opener and rated it "5/5".[3] Allmusic editor Stephen T. E. wrote that there's a lot to be said for professional craftsmanship at its peak and he called this song blistering plus highlight on album.[4] Alan Light praised the song: "Jam," the album's opener, addresses Jackson's uneasy relationship to the world and reveals a canny self-awareness that carries the strongest message on Dangerous. "Jam" features a dense, swirling Riley track, propelled by horn samples and a subtle scratch effect, and includes a fleet rap by Riley favorite Heavy D. Though it initially sounds like a simple, funky dance vehicle, Jackson's voice bites into each phrase with a desperation that urges us to look deeper. He is singing as "false prophets cry of doom" and exhorts us to "live each day like it's the last." The chorus declares that the miseries of the world "ain't too much stuff" to stop us from jamming. To Jackson, who insists that he comes truly alive only onstage, the ability to "Jam" is the sole means to find "peace within myself," and this hope rings more sincere than the childlike wishes found in the ballads."[5]
