As your combo's rank increases from D to A to SSS the music intensifies - the guitar kicks in, then the drums, then the vocals. Combo-chasing isn't just about big scores; it's about screaming music giving you feedback every time you get that little bit better. Only the the best players care about that letter in the corner of the screen, but by tying that letter to the music Ninja Theory has made it worth chasing that SSS for even the least capable players. Fight well and you'll look /and sound/ like a badass.
