Our first dance song was "Everything" by Michael Buble. I love the song, but it doesn't really affect me emotionally.
On the other hand, I walked down the aisle to "Stolen" by Dashboard Confessional and I get emotional/nostalgic every. single. time. I hear it. All those feelings of walking down the aisle come rushing back to me. I love it!
How about you? Which makes you more nostalgic?
