Pop Music
Often, pop music is confused with popular music. Whereas Pop music describes music that evolved from the rock and roll revolution of the middle 1950s and continues in a definite route today, popular music refers to music that is associated with the tastes and interests of the urban middle class during the period covering 1800s and industrialization to date.
From the 1950s until today, Pop music is identified as the hits most often played on radio, that which attracts the largest audiences, sells the most copies, and the musical styles that displayed by the biggest audience therefore it is really an amalgam of whatever is popular at any given moment and doesn’t represent any specific genre(s).
