I am not crazy about having “pop” songs to walk down the aisle to (I think it is more apprpriate for walking out of the ceremony to), so I will let someone else give advice on that.
However, I am a HUGE Ben Folds fan, and my husband proposed to me to that song. He also surprised me by singing “The Luckiest” to me during the ceremony. The last line of the song (the music notes) is also engraved in the inside of his ring, so The Luckiest holds a special place in my heart for many reasons, so I am biased when it comes to that lol. I say use it somewhere 🙂
