I need some song help for my mom's surprise party... ?

I'm making her a dedication power point: she's turning 50 this year and we're throwing her this mive surprise party. I've got pictures of her when she was a baby all the way to present day. The beginning slides are to "Just the Way You Are" by Bruno Mars, and I'm ending it all with Michael Buble's "Everything." What I really need is either one really long song (about 4 1/2 minutes) or two short ones that fill the same amount of time... It has to be good transitionally between these two songs. Help!
