Hi Everett the amount of plays has nothing to do with voting it is the amount of times your song has been played by people not judging but just having a listen to your song. Similarily if a song is selected as a fav this has also nothing to do with voting. It is just someone who has listened to your song independantly of voting they mark it as their fav.

The actual amount of times any song has been voted on is not published. I think it would make interesting reading though.
I suspect that some songs get more battles than others and this accounts for some songs being well out of position.
