Representation in music depends on genre and the social groups they represent, such as rap representing younger audiences and rock representing depressed teenagers. Will Smith started as an actor on The Fresh Prince of Bel-Air and later found success as a rapper with over 42 songs since 1997. His 1999 song "Wild Wild West" was written for the film of the same name and became a number-one hit, sampling Stevie Wonder and Kool Moe Dee. The music video featured steam punk imagery to symbolize machinery of the Western era. Cowboys are also commonly associated with representing the Wild West theme.
