In a broad sense pop is any music based on memorable melodie, repeated section (usually, but not always, verses and choruses), and a tight, concise structure that keeps the listener's focus on those elements. Pop music has been a profitable industry in America since the 19th Centure, but for these purposes, pop is a style that took shape in the post-rock & roll era, once the more conservative elements of the record industry had come to term with the new musc landscape. Pop emerged in the late 50's.

The big names in Pop are, Madonna, Michael Jackson, Kylie Minogue, Rob Williams, Boys Zone, Gwen Stefani, Britney Spears, J-Lo, Mika, Maroon 5, Lily Allen, Fat boy Slim, Christina Aguilera, to name but a few.
