Honestly, I have no idea how someone (who's as much of a music addict as I am) is supposed to narrow it down to just two songs. Here's Day Five of the '10 Days of You' Challenge.
This song played as my girls -- and then I -- walked down the aisle at my wedding. I can't hear it now without getting a little choked up. It was such a beautiful and special day, and this has pretty much become our song.
And this song played as my husband and I walked back up the aisle right after we were pronounced 'husband & wife' ... so it's definitely a favorite of mine.
