If you haven't listened to Smooth McGroove, go to his channel now and give it a look. Odds are you'll find a classic tune there you can resonate with, as he's covered franchises like Mario, Zelda, Mega Man, Sonic, and a whole lot more.
His newest video is Ryu's Theme, straight from Street Fighter II. Although it's a bit older, his Rainbow Road rendition is definitely something that will get you in the mood for another Mario Kart 8 race.
