Might be these sites build their own API or such to interact with Youtube. Youtube doesn't allow direct access to the database. It may even be that they use ripped copies of YT content
Other issue is that many Youtube vids have pretty low audio quality so it may be a nice add on for using some tracks but not likely a primary source for djing or vjing.
Could you also please register your Cross license if you have?
