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

I can only comment in terms of what stirs me:

”I’ll Never Find Another You”
”Never My Love”

I am not really fond of them, they simply hold tremendous sentimental value for some reason.

Oh my, what a neat question to ask and answer! There are sooo many to choose, but I'll limit to just a few that give me goose bumps...
1) Without You - Harry Nilsson2) I Want Your Love - Anthony Phillips(former Genesis)
3) Kathy's Song - S & G4) For Emily, Whenever I May Find Her - S & G5) Fields of Gold - Sting6) The Last Time I Saw Her - Glen Campbell (orig. by G. Lightfoot)7) The Coldest Days of My Life - The Chi-Lites

Danny boy.

I forgot to add this gem...Keep Me Warm - Cliff Richard

Nights in White Satin,  Moody Blues:
Days of Future Passed...
