I'm pretty sure that all of us love and appreciate music no matter what it is (as long as it's good). There is at least one song (or score) that probably makes you cry tears of either sadness or joyness, but probably more songs do. ^^
For me, my songs would be:
"Shattered" by Trading Yesterday
"For the Love of a Daughter" by Demi Lovato
"Eva" by Nightwish
"Stranger in Moscow" by Michael Jackson
"Edge of Night" from Lord of the Rings
"Rue's Farewell" from The Hunger Games
"Incomplete" by The Backstreet Boys
"Rain" by Breaking Benjamin
"Lily's Theme" from Harry Potter and the Deathly Hallows Part 2
"Love Song Requiem" by Trading Yesterday
"For You Only" by Trading Yesterday
"No Bravery" by James Blunt
I guess some of my picks lean more towards sadness...
