Thing is, does she have other ones she can do?
Assuming that show works like American Idol, then the answer to this will be apparent in subsequent shows.
And based on observing that show, she has mastered techniques that could easily be adapted to make a wide variety of pictures. There are a lot of pieces of music that she could use, and she demonstrates the charisma to pull that sort of performance off. I suspect that she will be quite successful.
