Thank you for the suggestions posted here! Sinearch ko talaga sa YouTube paisa-isa yung di ako familiar, and madami akong nagustuhan. I added them sa list for my reception songs. Para sakin, make or break yung SDE song. Even if you have a very good videog, if the song chosen isn't right, it ruins the mood and the appeal. Anyway, my contribution:
Little Wonders - Rob Thomas
*light-hearted and soothing
Miles Away - Years Around the Sun
*laidback and relaxed, perfect for beach setting
Flightless Bird, American Mouth - Iron & Wine (Twilight OST)
*solemn and deep
Good luck song hunting!
