The document discusses three different styles of music videos: 1) Narrative videos tell a story, like Bruno Mars' "Catch a Grenade" which depicts a man expressing his love. 2) Performance videos focus on the performance of the song without much plot, like Sia's "Chandelier" which connects visually to the song's theme. 3) Conceptual videos are based on an unusual or surreal idea, like Katy Perry's "Firework" which uses firework metaphors that can be interpreted differently.
