VERSUS rules are simple. there are 11 rounds based on U.S. Billboard charts, themes, and more. read thru the 11 rounds, and based on who served better songs/videos - vote for the best. i know some of yall will vote for your fav either way but whatever, try not to be too biased.  if you'd like, you can include your own score in the comments based on the rounds. example: "Britney Spears: 4 / Xtina: 7" have fun and don't fxck it up. ROUND: Britney Spears vs. Christina Aguilera
