I went for the HIStory tour version. Esp. when he breaks it down toward the end, with only the drum sound and one of the back-up singers shouting, oooh...sexy as hell. The part is addictive and I wish it didn't stop.
Almost all of the Billie Jean performances during the tour ooze pure swagga. He sounds like, moves like, um...he know it. It's like he's saying "Yeah I'm the sh*t!" without saying it the whole time.
