I can't even believe we're having this conversation.
First off, if you're going to do a comparison, at least do enough homework to find out who DID the original. To just toss it off and say "the original" is to show how little you care. I'm not even that big a fan of Don McLean. His original is an overly-long, obtuse take on the 1960s, which sort of obscures the basic song premise of the loss of innocence. But I think the core is still there, and it's a cool, interesting piece. (Bizarre production note - the song starts in mono, and gradually separates into stereo.)
Madonna's version is a dull, pointless, and soulless rehash. It's sung with little emotion, and even less feeling for what the song is about. (That is, unless Madge thought the song was about "having a hit single with a recognizable oldie". In which case, I guess she nailed it.) The only advantage of the remake over the original is that you can dance to it. But then again, I don't think the world really needed a version of "American Pie" to dance to.
The original wasn't actually that slow, other than the opening and ending - count the tempo if you gotta. And why shouldn't the song be "rednecky"? Listen to the chorus again. It's "them good ole boys were drinking whiskey and rye", not "my homosexual friends were drinking martinis and cosmopolitans." She and Mr Orbit took a song about going out to the country and getting drunk upon finding out your childhood heros died into substandard club fare. Perhaps that in and of itself is impressive, but it doesn't make the song any better.
I like Madonna. Hell, I even think that her original song on the Next Best Thing soundtrack was good. But this remake was lazy.
