Andrew Goodwin has a good theory, I guess.

Andrew Goodwin talks about narrative in different videos. He looks closely at Pop videos and says that they don't follow traditional narratives as they don't apply. He said that;
- Pop videos are based ont he song therefore the narrative isnt focused on
- Pop videos use the singer as both narrator and character
- The singer often looks at the camera to involve the audience, this breaks from the narrative.

Pop videos rely on repetition in their videos and songs to make the audience rememberer the genre, remember the song and remember the video all at once by sticking it into our brains and having it played everywhere (e.g. Radio, TV)

There are different types of narrative used to create different meanings and promote the artist in different ways. These are: Illustration, Amplification and Disjunction.

Illustration: This is where the video shows exactly what the lyrics are saying. In the music video Chainsaw by Family Force 5 they say 'Crank it like a chainsaw' and the action is shown.

Amplification: This is where something is shown to add to the meaning of the lyrics.
I had trouble finding an example for this one as most videos are quite literal and any extra meaning is subtle. However I decided on Lily Allen - Smile, this is because she sings about her ex cheating on her and trying to get her back. The lyrics 'with a little help from my friends, I find the light in the tunnel at the end' suggest that her friends were there for her and supported her through the breakup, however in the video it shows her 'friends' mugging the ex and trashing his house, and we get a completely different understanding of how she got over the breakup.

Disjunction: This is where the video and song have little to no connection.
In the music video 'Miss Nothing' by The Pretty Reckless, she sings about how she doesn't miss someone or anything about them, but she's just crawling around on a table the whole video.
