This is a video of the Konami game Jubeat.
A music game that centers around hitting little squares to the rhythm of the music.

Using a 4x4 grid of squares that play video beneath them the point of the game is to hit the square at the correct time, which usually goes along with the rhythm of the song.

The song is YMCA by the Village People.
I am not very good at this game, I just like it.

Enjoy.
