R. Kelly’s Chocolate Factory lead single, “Ignition (Remix),” reigned supreme as a certified banger in the early 2000s, earning him a No. 2 placement on the Billboard Hot 100 for five consecutive weeks and a spot on Rolling Stone’s 500 greatest songs of all time.

Along with the intro, verses and hooks, you’d think fans had grasped just about everything there is to know about the 2002 smash hit. What they didn’t know was that the remix actually preceded the original “Ignition” track, which Kelly just revealed 16 years later via Twitter.
