ibimus

I wasn't sure if this should go here or in the classical section....Mods, sorry if I'm wrong to post it here.

So. I'm auditioning for college this summer. I'm currently looking for some songs to sing. I need an art song, sung in its' original lanuage (English is fine, if that's the original language), and an aria from opera or oratoio literature.
I can sing in English and Italian, French is okay as well. (I'm still working on my Polish; not sure that it will be good enough to use in an audition.)

I'm a soprano, with a range of roughly three-and-a-half octaves. (starting at a low C and on up.) I have a fairly strong voice, so big belting songs are just fine.

Any suggestions?
