Simon and Garfunkel's "The Boxer" and "Bridge Over Troubled Water" are the first two that come to mind, though they have a few more. 
Scorpion's "Winds of Change" and Puckett's "Young Girl" come to mind, but they're painfully overplayed in these parts. :/
I've got a lot of these songs 'cause I'm a fucking puss. 
Lobo's "Me & You & A Dog Named Boo" gets to me. 
America's Unicorn musics.
