This is the moment Kelly has been waiting for for her entire life, I doubt she's going to give it up with SUBG or BTHE. BOY is her masterpiece and I feel it's the song she would want performed.

And Houster, I doubt they'd open up the show with BOY. That'd set the mood too low, they're going to want to open the show with an upbeat song. I suspect Kelly would perform closer to the end with BOY and *crosses fingers* accepts her Artist of the Year award just a few moments later :)
