I need to find a first-place worthy song to sing in my talent show.I need to beat the ultimate competition.?

I am going up against my toughest competition in my local talent show . My cousin. She use to be my duet partner until last year when she told me she wasn't going to compete. She lied. She went behind my back and paired with a fantastic singer. my mom made me sing an old--fashioned song that nobody knew. My cousin and her partner won 2nd place.I didn't even place. This is the last time me and my cousin can ever sing against each other solo. I need the ultimate song. I have a wide range and can hold out a note for a very long time. i want a song that is "up-to-date" and I want it to be winning material.Please help me find the perfect song. I appreciate you reading my question. Thank you for all imput you may add.

Well, Broken Wing and How far are very powerful songs, and I've gotten many standing ovations by singing them. Independence day is another good one. Also, I'm telling you I'm not going by Jennifer hudson from dreamgirls
