What is Popular Music?

Popular music is everything and yet nothing at the same time. A typical response to this question is that popular music is dependant on everyones own interpretation, I may have a different idea of what is considered popular music than someone else such as commercial music that is constantly in the charts or artists that are given more air time than other bands. This theory however is a misinformed identification with the genre of "pop" rather than the actual term popular music. The actual term popular music is relevant to any artist or band that appeal to an audience (no matter what that audience is), that sell their product for profit and use technology to create their music via instruments or other technological advances. Ironically this definition of popular music applys to nearly all music in the world which therefore implys that all music is popular rather than someones own opinion.
