speed fighter is a funky groove by Masaya Matsuura, founder of NanaOn-Sha. He's widely credited to be the father of modern rhythm gaming, innovating with the well-known classic PaRappa the Rapper. This track has some allusions to Parappa, see if you can spot the sample used in PtR2's loading screens! This made an appearance in Rock Band 4 as DLC, released in 2016.
Hope y'all enjoy this chart, and if I did this track justice, lemme know!
