I have to say, this subject's very interesting! I always thought that the Carnival Night Zone's music had a very Michael Jackson-ish vibe to it. If the Anonymous Source is to be believed, his version of the story actually does seem a bit more plausible. We know how Michael wanted to provide us with the best quality music he could come up with and with the Sega Genesis' FM chip, that wasn't really possible. Perhaps if this was developed for the Sega CD, things would have been different.
Also, did you know that an aspect of Sonic was actually developed with Michael in mind? Apparently, when they came up with Sonic's buckled shoes, they thought of Michael Jackson and the buckles on his "Bad" outfit. Interesting.
