WTH?!?!
Max, supposedly the entire second half of Sonic 3 was written by Jackson's songwriters. Compare Carnival Night to Jam and see what happens. I don't remember what Launch Base was similar to (though stylistically, it's obvious. It's the only hip-hop/rap-esque BGM in Sonic all the way until you reach Sonic Adventure.)
As to whether it's a coincidence, it could be. Either way, it's amusing. Also, then, consider the fact that the phrase "Believe in Myself" appears in, I think, every one of the SA/SA2 character themes. Yeah, it's the title of Tails', but it appears in the others as well (just noticed it in Fly in the Freedom earlier today).
