Musical songs for sopranos?

Hi, I am a 15 year old girl and i really want to sing a song in a concert, I want it to be a musical song. I sing songs like Memory form Cats, Defying Gravity from Wikid, Tis Mabel from Pirates of Penzance, I can sing songs like Phantom of the Opera and also songs like Queen of the Night. I have been musically trained and i want it to be challenging. Anyone have any ideas? x
