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

Hats off to Mickeyb for Grant Lee Buffalo and Honey Don’t Think….unique vocal style.
Can’t believe I’m saying this but, 
ELO - Telephone Line
stops me every time.
Unrequited love doesn’t really qualify as romantic…or does it?

How deep is your love - Bee Gees
Words - Bee Gees
To love somebody - Bee Gees
You're my home - Billy Joel
Annie's song - John Denver
My eyes adored you - Frankie Valli
