I am so late to this thread, and I'll admit I didn't read every single post. But what I have read, I will make this point, which is similar to what Laura said... I think it's very difficult to know who did what. Some clues are stronger than others, such as CNZ/ICZ/LBZ being done by MJ's folks... we don't know 100%, but I think it's pretty safe to say with 99% certainty. And the supporting evidence isn't exclusively tied to the makeup of the songs themselves, but the fact they were swapped in/out, in combination with what we know regarding legal issues and so forth. It would be shocking to find out these were done by anyone else. Some of the other music in the game isn't as easy to peg. I use my experience as a musician and song writer. It's very easy to make a song that kind of sounds like another song by coincidence. Music styles, theory, and influences get repeated throughout music generally. I'm not saying I think the efforts here are fruitless, but one must admit there's a very high level of speculation. When QJimbo's Sonic 3 was done, the case was being made for the ICZ and Smooth Criminal song connection, which I for one *never* bought into. Some of the other connections various folks on the internet made were just crazy to me, basically saying "oh yeah, this was clearly done by Michael Jackson" about songs that sounded nothing like his work, let alone the lack of evidence of his fingerprints being on any of the in-game songs. I don't want to come across poorly here. I encourage the efforts made here, but I am just not as optimistic about the ability to nail it down the way it really needs to be. We really need some concrete way of connecting with the composers in question.
