Does anyone know the top "love songs" of all time?

How about "My Heart Will Go On" from the movie TITANIC? Not my personal favorite, but the movie was such a hit all over the world back in 1998 (if i'm not mistaken). And everyone was like would sing along to the song whenever the song came out on radio, and anything like that. So worth top love song of all-time?
