Sven E Carlsson proposes a theory that music videos can be categorized as either "performance" or "conceptual" based on their narrative elements. For performance videos, the artist is prominently featured singing and dancing, exemplified by Rihanna's "Rude Boy" video. Conceptual videos emphasize artistic elements beyond just the performer, like Lil Wayne's "Lollipop" video which uses candy props and settings to tell a story beyond his performance. Carlsson also describes three types of performers commonly featured - the commercial exhibitionist, televised bard, and electronic shaman.
