What I thought music television would look like

I remember hearing, in seventh grade, that there was going to be music television. I was so excited to see it because for some strange reason I thought that the music would be visualized -- it would come to life through color and shape and we would all enjoy it all the more. It turned out to be lots of folks with long hair in tight pants. But now, thanks to the interwebs, we are coming close to such visions.

If this isn't a dream fragment from the mind of 13th century mystic Abraham Abulafia, I don't know what is.
