For me I always loved the song "You're the Inspiration" by Chicago I think. But I really like the song "One Dance" by Jodi Benson because it goes with my theme and I think it would be a great song to do a slighty choreographed routine too (we plan on taking some dancing lessons) But I want a song more timeless I think. I loved the dance they do at the end of Enchanted and think it's just so romantic (and I'm so not mushy mushy) but that song doesn't really work for a wedding.
But in the end DF said he wants to choose and I said yes, so right now we are still undecided.
