The first one I find romanic and beautiful is
It has a simple and steady beginning, then building up the atmosphere slowly, gradually opening to a subtle yet warm and positive ambience. I feel a sense of long lasting happiness and joy in a relationship. Nice work!
The second nice Valentine's day music is
A lovingly warm piece of music, creating an ambience so gentle and calm, like a couple so much in love. It serves very well as background music for love theme projects too.
