Song for a musical audition? I really need help!?!?

Question:I'm trying out for Sound of Music at my high school and I can't choose a song. There are alot of really good singers at my school, so it needs to sound really impressive, but still be pretty easy.
I have a pretty good range, my most comfortable area, though, is from B to E (not the E 3 notes up, but an octave and 3 notes up, lol), and inside that range, especially G to D.
Thanks so much for all your help!

Do you watch High school musical? Or Hannah Montana? I prefer 'True Friend' or 'Gotta Go My own Way'.

are you singing a song from the movie, or are you singing any random song? Do you need an accopmanying track, or sheet music?
