I have this experiment in mind...

Basically if people were to post links to music videos on youtube, I would create a blank youtube account, log in, "like" all the music videos that I and the rest of the community like, and see what the suggestion box does.

For this to work, some consistency is required...

My theory is that there might be an intrinsic duality to the charachter of music the community enjoys vs the charachter of the music that is listened to generally and its possible that the AI/Social Network Map that powers this box may be able to define it.
