Editor's note: Yesterday, in the final hours of voting, this bracket came under siege by "spambots." These bots made a late-breaking push for a specific contender that shall remain unnamed. (Sorry, Brandon Flowers enthusiasts.) We've ID'd and removed the fraudulent votes — these are your real final two.
No. 1 "Rolling in the Deep," Adele (2010) vs. no. 3 "Hey Ya!," OutKast (2003)
