What's people's classic/well-known super-positive song?

When you find some young girl has appeared in your life, and she makes you feel on top of the world.. some already-loved classic tune speaks to you while you're in your state of bliss.

It might not even be intended as a girl love song at all, but you find some gold nugget within it that just speaks to your own girl-loving heart.

What is it?

I'll start.

Sugar pie, hunny bunch..
