[Sonic 3 & Knuckles: Project Chaos - History]

Maybe it's just me, but the inside parts with the character silhouettes look like they should have a brushed steel finish. I hadn't commented before because I assumed that's what you were going for.

That is all, excellent work so far; eagerly awaiting this project with ongoing anticipation.

The old-style synth was my favorite part of this interesting mix, though it made me think of Pac Man more than Mario. I don't know why everyone thinks it's off-key, sounds fine to me.

[OCR00598 - Super Mario Bros. "Underworld Rock"]

LibertyCabbage is probably referring to "8-bit Eighties", it has the underworld music mixed with that annoying cheerleader song (hey Mario you so fine, you so fine you blow my mind...).

Underworld Rocks has always been one of my favorites upon finding this site.
