What piano pieces should i play for my HSC practical?

i have to play 4 songs that have lots of emotion in them. I'm on grade 5 but don't mind trying harder pieces. However i will only stick with the song if i like it, and unfortunately get bored with mozart songs etc quite quickly. I already know i wil play jessica's theme from man from snowy river, and perhaps the heart asks pleasure first by michael nyman (from the piano.) I really like ludovico einaudi. I'm open to any suggestions!! thanks :)
