Just because Beyonce can sing something, doesn't mean you can. That's why she makes money singing, and you don't know enough about your own voice to pick songs suitable for it without asking a bunch of strangers who don't know what you sound like or what you even need the song FOR.
Here is a good song for a powerful mezzo soprano voice---just to prove a point you need to give some details, and not all mezzos necessarily can or should sing the same songs:
"Stride la Vampa" from Verdi's "Il Trovatore"

Really, dear. If you have a voice teacher or SOMEONE who actually works professionally with singers (even a choral director) who has heard you sing, please ask that person for help choosing a proper song that will show off YOUR voice and singing ability. Only inexperienced singers pick songs based on what they sound like when other people sing them.
By the way, I CAN sing that aria (complete with the trills), but SHOULD I? Nope--not good for my lighter lyric soprano voice and certainly not compared to one of the greatest mezzo-sopranos who ever lived (and is still alive).
