The document discusses several music videos and their purpose in promoting artists. It notes that Katy Perry's "Roar" video promotes her in a positive light by showing her strength and ability to overcome obstacles. Nicki Minaj's "Pills and Potions" features advertisements that promote both her products and those of partner companies like Beats. The Kongos' "Come with Me Now" focuses more on other people than the band but still promotes them by featuring their song. Lady Gaga's "Artpop" film attempts to portray music videos as an art form rather than purely promotional, as suggested by Andrew Goodwin.
