What song should I sing for my "The Voice" audition?

ok so I have an audition for "The Voice" July 15 and I have to prepare 2 songs. I already have the first song it's "Lovesick Blues". I need a second song. I have a range that goes from Contralto to Second Soprano. I also really love old classic songs that everyone knows cuz their just awsome but anything is welcome. Anyone know any good songs for this? Id appreciate anything =) thanks
