What is 'pop' music?

Pop music to me is music that makes it into the charts, whether that is classical music to RnB it is 'pop' music.  Music which in the words of Robert Burnett is "Commercially Orientated" well know music that has alot of radio air time. Throughout the years the view of 'pop music' has been seen in a variety of ways due to the connotation of the word 'pop'. Only in the 18th century did it start becoming a posotive connotation. Is pop due to beeing accessible? I wouldnt say so, due to so many variations of media technology access to varieties of genre music should not be discriminated as means to be biased to pop music . Music as a whole has become profit orientated, yet pop gets the connotation for money being a primary aim. 'Pop' an abbreviation for popular. Popular music will always be the music prifting in the industry.
