If by some miracle you haven't grown sick of Gangnam Style yet then Just Dance 4 is for you! Featuring the K-Pop hit along with a stack more tracks from across the pop charts, Just Dance 4 is a competent party game. It's little more than a novelty at full-price, but at a discount it's worth grabbing for whatever get togethers you're having in the new year.
