What Is The Most Romantic Song That You Have Ever Listen To?

There are so many, but two that come to mind are Gato Barbieri's Europa, and Van Morrison's Wild Honey

Too many to list, so 3 suggestions. 1st is from the '60s but I didn't hear it 'til 2 years ago. 2nd is very recent. 3rd is classic bossa nova.  All 3 are quite romantic (and blue):

My first post, Nat King Cole, That’s All.
I can only give you love that last forever 

First - Johnny Mathis was the KING of makeout music in the 50's and 60's with "Chances Are", "Wonderful, Wonderful" "Misty", "The Twelfth of Never" -  Tommy Edwards "It's All In The Game", "Please Love Me Forever", "Love Is All We Need" -  Perry Como "And I Love You So" - Paul Anka "Put Your Head On My Shoulder", "Puppy Love" - John Gary's version of "Unchained Melody" - Nat King Cole "Unforgettable" - The Lettermen "When I Fall In Love", "The Way You Look Tonight", "Portrait Of My Love".- Jesse Belvin "Goodnight My Love" 

Romantic songs always sound more romantic thru a $100 fuse.
