What Is The Best Black Sabbath Song Ever?

Yesterday, we asked what the best Ozzy song was. After tallying the votes, Crazy Train was the most popular...but that was his solo stuff. We all know the Prince Of Darkness would never be where he is today without the (arguably) best heavy metal band of all time, Black Sabbath. Vote for your favorite Sabbath song below, and we'll post the winning video tomorrow. Choose wisely, 'cause if you don't, Bill Ward may quit...
