Michael it all depends on how many people are judging. If there are thousands then 1 person voting for their own song will not make much if any difference. It would be interesting to see just how many people are judgeing in the categories. It is not like normal voting on other sites where you can vote for you song sometimes multiple times. It is very hard to jack up any song just by judging one song against another. I think the biggest thing that causes problems and unfairness is being allowed to vote same. This should be stopped. I am sure that there is always something that can influence you to vote on a song being better than another. Whether it is tune, arrangement, lyrics, performance, recording or even artwork there is always something to seperate each entry.
