Eurovision

A report today shows that the public vote was almost totally opposed to the vote of the judges panel, this raises the question if a huge number of the public like song A why is the small judges panel voting for song B?  Now I know a lot is down to personal taste, but I can't help but think theres more going on here.  Maybe it would be fairer to have ONLY the public voting in all the countries, insted of a  judging panel selected by who exactly???
