So I saw jazz-ballet's thread about that song Alex Chilton and checked out the YouTube video.

Then I see The Replacements is written in blue in the title, and that it is a link. So, being the daredevil that I am, I go and click it and find this:
http://www.youtube.com/artist?a=GxdCwVVULXdE4yS5VXxXVAyu7rJwDsLD&feature=watch_video_title

How long has this been going on?
Can you search for artists to see their page, or can you only get to it through their music videos?
Are these links coming to all music videos, or is it a lottery?
Is YouTube making these pages or are they user made?
Does YouTube put the link in your video automatically, or do you have to do it?

Whatever the answers, I for one would like more of this plz.
