Soft, tender loving background music help please.

I want to make a slideshow of pictures of three little girls I love very much. But I need nice, soft, loving music.
music that goes well with cute little faces and poses.. lol

so far i have "What a beautiful world" and by louis armstrong

and "somewhere over the rainbow" by Israel Kamakawiwo Ole'

and so far there isn't one person that doesnt jerk a tear with the cute pictures and those songs playing in the background..

any other ones you all know about?

How long does the slideshow last just enough for 1 song or a few?

Upside Down by Jack Johnson. Or anything else by him.

Well, I hope to make it as long as possible.
The longer, the better. and... i have little videos that I'll will use too so it's more of a movie than a slideshow.
i have plenty of pictures, i need the songs for the background..

im hoping for a show around 20 mins.. maybe less, maybe more..
