It's a big deal for games to incorporate popular music. You might find today's hits blasting from a car radio or a street basketball court . Music can also be a more integral part of gameplay such as in a dancing or karaoke game. The TFD template in Figure D.6 reflects the player's ability to add and delete songs, order them, map them to game events, and trigger them from within the game. Depending on the game, triggering could be user controlled ‚ such as tuning to a particular in-game radio station ‚ or event-driven like the music played when the home team scores a touchdown. Just remember that "New Order" on the TFD refers to the order of songs in the list, not the electronica supergroup.
