So many excellent choices on this list (really liked Ken's nod to Singing in the Rain). I'd add:
"Time in a Bottle" - Jim Croce
"Hurt" - Johnny Cash
"Dancing Cheek to Cheek" - duet between Ella Fitzgerald and Louis Armstrong
"Pussywillows, Cattails" - Gordon Lightfoot
"Don't Take the Girl" - Tim McGraw
"Last Kiss" - Pearl Jam
"Say Something" - Great Big World
"I Want You Here" - Plumb
The Schindler's List soundtrack
(Yeah, I know, I have an eclectic taste.)
