The successor to Frequency, which saw many improvements. Including a visual style that isn't senseless, more popular songs (likely from Sony's publishing power), and a more refined design that more heavily promoted perfect runs and chains. Granted, the latter was still exceedingly tough on higher difficulties.

There isn't much to speak of outside of this, as there's no real narrative. My one complaint is that the lanes get a little too "hill-y" and make it more difficult to see the oncoming notes. Regardless, this was still a solid rhythm game with a unique design, and something that would creep up in Harmonix's career from time-to-time while in the midst of their Rock Band craze.
