I've said it before but "Seasons In The Sun" just instantly dpresses me and makes me cry like a kid!
In fact when I was a kid in 1974,I didn't "get" the lyrics but somehow my mind grasped the mood of the song and it made me cry.
My Mom & Dad could not understand what it was I was crying about,heck,I didn't know myself!
Others are,
"You Needed Me" by Anne Murray
"The Three Bells" by The Browns (1957/58)
"If" by Bread did for a long time but not anymore.
"Calypso" by John Denver brings tears but not of sadness but because I get so into it when I listen. :D
"Concerto In D-Major" by Vivaldi used to make me cry,until when I fell in love some years back.
I came to realize it was actually quite a beautiful romantic song.
(I played it on "our 1st night"

).
