Sorry I'm only just getting to this now, but I'm here now to elaborate.
When I originally paired these tracks, I did it with the intention of strengthening my analysis for who composed which Sonic CD tracks. Despite having plenty of evidence beforehand, this served as a finishing touch, making for a perfect cross-referencing. The bonus was that it also made S2GG that much easier to crack. (Honestly, though, I didn't expect that would happen when I started. I just noticed the similarities between TT and Crystal Egg and never looked back. My mind was blown like the others I've shared this with.) [Side note: It turned out I was 100% right on composition credits when the OST dropped, though I was mistaken for the arrangement credits, so these are factual to some degree given their similarities.]
First things first: If you want to hear the similarites, you need to adjust how you hear each song. A CD song won't necessarily sound the same on 8-bit; after all, the latter can only do so much. Anyone who knows a typical Master System port of a Mega Drive or arcade title should know what I mean here. Rather than take the obvious connection between Green Hills Zone and Sonic - You Can Do Anything (the former benefiting from the vocals being the main part), instead take
Mecha Green Hill from Sonic Chaos, especially from 0:38 to 1:07 [0:19 is the bridge, 0:42 is the chorus], for it is based off of Green Hills Zone.
What you want to do next is count beats. Once you see how those are similar, you should start to hear the shared melody between the two.
After that, you want to count sections and compare them to their paired CD track. Once you see the similarites in section numbers, you'll see how the composition process is similar.
