Alto Audtion Help?

I'm a 16 year old alto. I've done lots of community theatre but I've been ensemble, featured dancer, small un-noted parts, but never a lead. This summer I really want to finally earn a part in their next show so I'm already starting to work on my auditon. My question is what are good audtion songs for alots my age? Also what type of monolouge is best to use? I've used both comedic and dramatic.

It's just for the single show. It'll be in the summer. I've heard it might be Willy Wonka and the Chocolate Factory. It'll definitly be a family show becuase the summer show always is.
