5. "Halo"
The "I Am… Sasha Fierce" standout earned the fifth most votes in the poll, with Beyonce fans narrowly preferring the power ballad to "Countdown" and "Irreplaceable." This might make for an emotional set-closer, a la Madonna's "Like a Prayer."


4. "Love on Top"
Sure, the "4" single radiates joy, but will any live performance of the song top her rendition of "Love on Top" at the 2011 MTV Video Music Awards, which featured the expressive "I'm pregnant" belly-rub at the end? Fans seem to think so, and swiftly voted this pop tune into the Top 5.
