Oh gosh...
If you must use Beyoncé, PLEASE do it in the exhibition!
I'm not exactly a Beyoncé fan to begin with, and I almost always hate competitive programs with pop-especially bubblegum pop *shudders*-though there are a few exceptions. So this Beyoncé/gatsby/everything 'poppy' that exists craze is not really my thing. I liked phantom better. Heck, even Carmen-which is decidedly not my favorite-would be better.
Leave the pop for your exhibition program, please. That's the point of the exhibition.
(I must say, though, I'm rather curious about Florent's "Happy" SP )
I think there is some pop that can be usable for competitive programs. Like Bruno Mars. I don't know, I just try and listen to some songs and think if the vibe works or not. Jesse McCartney songs might work as well.
