Nowadays, without sound, there would be no game. Well, there would, but it would be a somewhat crap game. I know there are games that are still epic when played without sound like ‘Tetris,’ but with high consumer expectations and progression of technology, sound is a very important aspect to games that determine their overall experience.
Sound used in ‘Tekken’ makes each character unique to give them personality and background. In ‘Tekken Tag,’ the character named ‘Unknown’ has a stage soundtrack that suits her well. This character is under the control of an evil spirit in the form of a wolf and the composed music fits perfectly.

An example of a game where the sound effects and music have a lasting effect on the player is in ‘Left 4 Dead.’ As you shoot the infected in this first hand player game, you may encounter a witch and the game warns you when you are approaching her with creepy music that becomes louder as you get closer. And what really created the eerie atmosphere is the disturbing witch’s crying sound effect with the backing music. Sound is a warning of on-coming danger in this game and creates tension. If the game is played on mute your character is as good as dead.

Nile Rodgers/Bernard Edwards composition 'Good Times' signalled the start of the take-off of hip hop music, and the song contributed to the success of the Sugarhill Gang's 'Rapper's Delight,’ the first-ever hip hop record. It was this same song, with Edwards’ catchy bassline that influenced Queen's John Deacon to write the hit, ‘Another One Bites The Dust’ in 1980. ‘Good Times’ is a prominent recording but I can’t say if it was the most influential recording of the 20th Century since I haven’t heard enough ‘influential’ music in that time to judge.
