Weddingbee boards

I'm trying to put together slideshows of our wedding/reception and tea ceremony/banquet pictures to show family members in China that were unable to attend either event.  There are a lot of pictures, and trying to get them to fit one song creates a slideshow that goes too fast and gives me a headache, lol  I want to use Train's Marry Me for the wedding slideshow, and OneRepublic's Good Life for the banquet. Does anyone have suggestions for contemporary songs that would fit well with those in terms of theme, rhythm, style?
