I love both. I vote for Beyoncé because it is such an epic collaboration!
Why can't people act like mature human beings and answer the question without shading the other artist you don't pick? Get a life! Talk about being petty. Not everyone has to agree with you, and your opinion IS NOT FACT.
Britney Spears stans are so pressed and insecure about their fave. Why do you have to create all this thread about Beyoncé? Clearly Beyoncé is a threat to you.
