I had a web app to do this a few years ago (2011?) For thematic music video content at http://80smtv.com/#80smtv (still up but a ghost town).

Here's the source (https://github.com/kristopolous/emptyv) ... most of it was written during the 3 or so weeks that it had lots of traffic, coming from all places, Poland.

I worked hard on the anarchistic anonymous vj feature as a social experiment. It was interesting but not traction building.

One day I'll build something that can sustain traffic. One day...
