Songs for talent show.....?

so im singing at this thing at my church. its like a little talent show. im trying to decide wat song to sing. right now i like "beautiful" by kari jobe. and "o, america" by celtic woman. i want some other options too tho. i want something soft and beautiful. nothing pop or rock. it will just be me and a piano. i dont really want it to be sad either. thanks!
