The originators of the Pop Art were Claes Oldenburg, Andy Warhol, James Rosenquist, Roy Lichtenstein. The movement emerged in America and Britain in the 1950s.
The Pop Art movement started as a reaction of the nonrepresentational nature of abstract Expressionism. The movement reintroduced the identifiable imagery. It broke the notions that high art does not belong to low class. An art has nothing to do with the class.
Film music can convey many emotions and settings, sadness and happiness, a rural countryside or a dark forest. Anything. Hope this helps in some way :)
