I think the 'slow' version is very good. But to say that it is better than the original isn't really being fair - the original was a funky jolly tune that was great fun to listen to. Even though the song is the 'same', the two versions are different enough to be judged separately. Without the original, there wouldn't be the 'cover'.
Which of these artists claimed to be "down with black culture"?
Are we not allowed to listen to music by other races? And then possibly derive enjoyment from this listening?
And then possibly cover their songs?
I agree, though, if someone ever actually says "I am down with [whatever] culture", they are pretty lame.
