Every song we've liked are essentially break up songs...(not that we chose to, just we like the music & that we can sign to it...didn't realise until today what the lyrics 'meant' as such.)
EG:
Vanessa Carlton - A thousand miles
Astrea - You're not alone
The songs we already have for the ceremony;
As guests come in Ed Sheeran + Pacabel - Perfect ft. cannon
My walk down the aisle James Horner - My heart will go on
When we exit as MR + MRS King Counting crows-accidentally in love
