Song suggestions which would suit my voice?

I'm going for an audition soon, for a main part in a musical. I need
to sing as part of my audition only I don't know what to sing. I need
some ideas for songs which you think would suit my voice, then I could
listen to the songs and choose between them.

My voice is like a sofer version of Pixie Lott, a few songs which I
think I can sing well are:
Use Somebody
My Heart Will Go On
Fields Of Gold
Ave Maria
Run (Snow Patrol)

What other well known/old songs do you think would be a good idea to
try.
Please help me. Thankyou alot xxxxxxx
