What are some romantic songs for 1st soprano female singers?

I would like to some recommendations for songs to sing from musicals
and from the 50s to 2011. I would like as many ideas as possible. I
would be singing the song acapello (sp?). I have a three octave range
and I'm a voice minor, but my mind is just going blank right now! I
can't really sing country, but I am not opposed to singing any country
songs at all. Thank you all so much!
