Ladies and Gentletens, the moment you've all be waiting for: It's time to cast your votes for the Song of the Summer! You've submitted your nominees, we narrowed-down the field, and now just 16 songs are competing for the crown.
This year, we've set-up a bracket system, so we'll be voting in four rounds. The first round of voting will only last about one week, so cast your votes now. Will the top seeds take the day, or will we see an upset? Can Bieber steal Carly Rae's thunder? Only you can decide that.
