So, this is a discussion thread about Google and third party "matching for videos". I'm not clear what the problem or opportunity is that you are asking about. Who is the "third party". What type of videos? Are you producing them? or copying them? Or just trying to find them so you can promote them on your website? Can you give more info?
You should make your own videos and don't use copyrighted songs, you can use Google Audio Library for free music and sound effects
