Muzak

       The next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear?   71   It's similar to the music you listen to, but it's not exactly the same. That's because this music was especially designed to relax you, or to give you extra energy. Sometimes you don't even realize the music is playing, but you react to the music anyway.

       Quiet background music used to be called "elevator (电梯) music" because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name "Muzak". About one-third of the people in America listen to "Muzak" everyday. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired.     72

       If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don't want their songs to be used as Muzak, but others are happy when their songs are chosen. Why?   73
