It is strange, therefore, that the original game had nothing in the way of party modes. Thankfully, DJ Hero 2 rectifies that. There are a ton of multiplayer modes being added to the game, the most exciting of which is the "Party Play" mode. This allows players to drop-in and drop-out of the game seamlessly, without ever stopping the music from playing. So you can use DJ Hero 2 as background music at a house-party, but you can also let people jump in and out of the game as they choose.

Neat. Other modes bring back the rewind functionality from the single-player game, aswell as DJ Battles and new Checkpoint matches.
