What song should i sing for the talent show? HELP!!!?

well i thought about singing scars by papa roach or creep by radio head but im a saprano and a girl so it would sound wierd. i know i want to sing something emotional cause thats just who i am and something alternative nothing pop or anything. i hate pop no offense to those who enjoy it. by the way last year i sung fall for you by secondhand serenade and won. well if you have any ideas id love to hear them. :D
