Help? I need to choose a song!

Auditions for my school variety show are coming up, and I am determined to learn a song and try out. I really want to get in, and impressthis guyeveryone. Of course, I can't choose a song. From a list of 22 songs last night, I've narrowed it down to 4. Yes, 4. And I've asked a bunch of my friends, and guess what? Each one said a different song, and now I'm back to square one. I have 4 songs, and not one is liked more than another.
So now I get to ask Mibba.
What song should I do?

-Come Home, by Eyes Set To Kill;
-What If, by Emilie Autumn;
-Shallot, by Emilie Autumn; or
-Nemo, by Nightwish?
