Sven Carlsson theorized that music videos can be categorized as either performance clips, which primarily show an artist singing and/or dancing, or conceptual clips, which show something else to create an artistic effect. Carlsson also noted that a common analysis technique is to view music videos through opposing binaries like trash/art or commerce/creativity. Additionally, he believed that performance videos often transform the performer into a "commercial exhibitionist" used to sell their image rather than remain the protagonist.
