I think I was with you up until you said the AAF version of "Smooth Criminal" is better than MJ's.
Here at Das Base, I try to make sure that I'm at least open to others' views on art. So I schlepped on over to Kazaa and grabbed the Michael Jackson version. After all, it's been a while since I heard it; maybe the one I heard was crappy. Downloaded in a few seconds (I love broadband) and fired it up. I gave it a full listen (my roommate fled after the first verse; he's MJ-averse, apparently), but I still don't see how it beats the Alien Ant Farm version. But, to its credit, I heard the AAF version first, so maybe it's more about what you hear first than what is "better"
