18. Chemical Jam - Sonic X Charles Barkley fanfic included
Remember what we said about 90's and 90's? Here we go. Despite the thumbnail, the first of three Sonic-related entries has nothing to do with the Adventures of Sonic the Hedgehog cartoon. Rather, it's a remix of the popular Chemical Plant Zone ("Chemical Jam," get it?) theme from Sonic the Hedgehog 2, which basically means that this is the theme of the most popular zone (if Sonic Generations is anything to go by) of arguably the most popular Sonic the Hedgehog game, which was one of the most iconic games of the early 90's. It's so upbeat and 90's that it almost hurts, but at least it hurts so good. Plus, it's probably better than the new Sonic Boom video games.
