After falling down an unrelated rabbit hole on Twitter, I stumbled upon this incredible remix of the Chemical Plant Zone theme from Sonic 2 by yell0. What you hear is a suped up version which somehow sounds even more 90s than the original. It hit my nostalgia bone and made my leg kick out (at least emotionally).
