Band Mashups plays much like Guitar Hero, but in reverse: notes scroll up from the bottom. Each "note" is a motion from the Wii remote: left, right, down and "stab" with the Wii remote, all done to the beat of the song. Planet Moon has done an impressive job visually representing the motion of the players' Wii remote: at the top of the note scroll is a needle that's moving in relation to how little or how much you're motioning to the left or right. It's one of the coolest and one of the most impressive implementations of displaying accelerometer motion in a third party Wii game so far… and it's far better than games that just give you a "thumbs up!" after a left or right motion. In this game you know you're waggling because it's being displayed in real time.
