Genre theory in music videos

Genre as a system theory.
In different types of genres, many people have expectations on what a music video would have. Media texts meet audiences expectations through generic conventions. Jon Berger argues that the way and texts are interpreted are based on the interpreters perception, belief, pas, history and interpretation of events. 

Below I will give examples of specific music videos that conform to the repetition and difference.

This music video on the left is called Trust and Believe song by Keisha Cole.
The music video is a story about a females hear that breaks as her boyfriend cheats on her with her best friend. Many young people can relate to this story as this conform with Jon bergers theory which I stated earlier "ways of seeing". In many R&B music videos you will always expect to see  a story line that has to do with relationships as well as in the Iconography you would expect to see the style of the singers performance in the video, wearing expensive looking clothing, and shoes branded shoes/heels and the singers hair groomed.

Moreover, audiences would also expect to see huge, expensive, cars, as well as luxury houses with swimming pools with a great view, gardens. In an R&B video audiences would expect to see the performers singing on the street, singing their souls out. At the end of Keisha's music video, her boyfriend dies in a car crash with the best friend after they were caught again in bed. Most people would expect something bad to happen at the end of the story because the Keisha was really heart broken, hurt and many females would not forgive.

This music video on the right is called Foolish song by Ashanti. The repetition in R&B is that it is often about relationship, being in love and arguing. Similarly to Keisha Coles's video Ashanti's boyfriend cheats on her. There use big mansion house with swimming pools, Hammer cars, the blinging jerwerys   Where as her Ashanti's boyfriend was also a drug dealer that she later on finds out about with disappointment. And also there difference is that at the end of Ashanti's music video at 4:03 she stays with her boyfriend which this subverts there stereotype of what people would expect, people would expect her to not be with him anymore.  

Furthermore, hybrid genre is a combination of two or more stylistic, themed categories. Such merging may occur in art, music..
