Andrew Goodwin's theory suggests that music videos primarily serve a promotional purpose by highlighting the artist, their products, or movies. Examples include Rihanna's "Umbrella" video promoting her as an artist, Pharrell's "Blurred Lines" promoting Beats pills, and Pharrell's "Happy" promoting Despicable Me 2. However, some argue music videos can be artistic by entertaining audiences or telling a story, like Michael Jackson's "Thriller" or Eminem's "Stan". Most videos likely have elements of both promotion and artistry, but some lean more one way than the other.
