6. Janet Jackson, Justin Timberlake, Jessica Simpson, Nelly, P. Diddy, Kid Rock - Super Bowl XXXVIII (2004)
Janet Jackson's Super Bowl performance is, alas, mostly remembered today for her "wardrobe malfunction" alongside Justin Timberlake. That alone made it one of the most talked-about halftime shows ever – leading to a five-second TV delay for all future performances, not to mention a protracted legal battle over FCC censorship that lasted until 2012. And, oh yeah, Nelly, Diddy, Jessica Simpson and Kid Rock also performed at that show. But really, who remembers those minor details?
