Hey, Dave(the ancient mariner), you listed my first choice, My Love Is Like a Red Red Rose. And Burns wrote to a friend that he would have to publish that one himself because neither of his publishers would like it. Burns was right. The First Time Ever I Saw your Face, Eileen Aroon, and Lagan Love, are right up there. Breaking the rules of the thread and stepping outside "folk songs" the Italian art song O Sole Mio is about as romantic as a song can get.
