Music videos are created to enhance the story that is being told through song being sung. In many cases we go so involved in singing the song that we don't really pay attention to what is being shown in the video! Take Katy Perry's "Dark Horse," for instance. It has a very catchy hook to it but did you realize there were a couple of dogs, some cat people and some really weird Egyptian stuff in the video too? You'll soon see this stuff as you watch the video without the music, but there's a good chance you'll end up singing the song as Katy mouths the words!
