What are some good love songs on an acoustic using standard tuning?

Question

I'd rather not re-tune my guitar. I'd like to play a song for a particular person and I really want it to be semi-impressive but not that difficult to learn. Just as a side note, if there's anything by Dashboard Confessional that is in standard tuning, let me know.

Answer 1

you can play lips of an angel by hinder or wonderwall by oasis  

Answer 2

everything i do by brian adams.

Answer 3

You could play "Slide" by goo goo dolls. or "Comfortable" by john mayer. They're a little more difficult but definetly do-able
