Popular music is said to reflect the tastes and preferences of which social class? upper class, middle class, lower class, underclass

Popular music is said to have the widest audience and is believed to be the music of the Middle Class (this is the correct answer); the Upper class would listen to other kinds of music, such as Jazz and very specific kinds, while the Lower Class is said to listen to "folk music" -althought this might be changing, just like the definition of what is popular music is changing all the time.

The answer is Middle Class.

Many people in the Upper Class would prefer the classical music.  Classical music signifies status and class of a certain group of people while Popular Music often influences the Middle class or sometime the lower classes because this music is often heard by people in radios.
