First song

I like this tradition for weddings. It is one we are keeping (we are nixing many others). We had a song that I like to consider "our song" very early on. It was a bit of a pop song, but not well known at the time. Well, now, it is so well known it was nominated for a Grammy and we heard it used in a commercial a couple nights ago. The MOD put the final veto on it when we saw that commercial. But now, what is a good first song? I am working on a list for him to peruse and see what he likes. Our tastes do not always match when it comes to music.

Any suggestions?
