Due to the curious nature of the background muzak played in the Terminal, how do you handle the musical mood changes? For instance: when a certain PC's angry, do you swicth to heavy metal; when sad, do you play a melancholic tune, etc.?
When I tried to do that, I found several problems between each players, so no music when I'm the GM. No time wasted looking for the track that - maybe - fits in the scene.
Maybe I will try to use music again, only for the background, but I will not care to change it during the game, just one long track. If you can describe the situations and the feeling of, and if your players are "in" the game, they will feel the pain, fear, happiness... whatever you want.
