Snoop Dogg and Pharrell Williams released a song called "Drop it like its hot" (2004) which minimalisticly yet powerfully encompasses these themes. "The expression is basically a call for a female to perform a suggestive dance (usually directly in front of or with a male) that involves shaking her lower body until it touches or nearly touches the floor." (Wikipedia). In the video women shake their booty in response to Snoop Dogg's lyrics along with images of marijuana, cars, pimping, etc. Songs like this that are actually themed on tropes of the 'commercial' gangster rapper culture, deepen their overall associations with the Hip Hop genre and its ideals. Music video's are often the first and sometimes only times that we are able to see songs gaining visual definitions and/or affirmations. Music videos have the power to not only give a song life, but instill visual representations, whether they be positive or negative, within our minds. With the abundance of 'commercial' representations of Hip Hop being put on mainstream television, it is easy to see that society's views on Hip Hop ideals and history is derived from the Gangster Lifestyle.(Wikipedia - http://en.wikipedia.org/wiki/Drop_It_Like_It's_Hot)
