Does anyone know any good songs to sing for a girl entering a singing competition or a show?

Try who you are - jesse j
blown away carrie underwood
he wants it all - forever jones
warrior - demi lovato
skyscraper = demi lovato
chandelier - sia
titanium - sia
diamonds - rihanna

I sung "Somewhere over the rainbow" with my cousin. It's short and kind of kidish, but a good song.

Demi Lovato - incase
