The Video Question

Recently, when I posted about musical "soul" a new reader, Lincoln Hunter, posed this excellent question as a result of a video I embedded:

Why does so much music come with a video? Do I need it if I have a soul for music? Isn't the video a diversion, a distraction? Am I not being manipulated by the video? . . .  I really would like to hear someone explain the use of video with a piece of music. Perhaps you will have time to answer in a post in the future.

Why marry music to video, indeed? In my response to Lincoln, I mentioned that I prefer music on its own terms -- as a lone art form. But, I am certainly a member of the video generation . . .
