SAD SONGS

Beethoven's "Moonlight Sonata" does that for me...as well as "Trilogy Of The Damned" by Evergrey, "Home" performed by Michael Buble, "Little Wing", or "The Sky Is Crying" performed by Stevie Ray Vaughan, and "Hello" by Evanescence are a few that I can think of right now...
 
I think Suicide Note pt.1 is sadder than cemetary gates

Martyrium - Tears From the Demented Heart
Pagan's Mind - Search For Life
 
Mourning Beloveth - Narcissistic Funeral
Mourning Beloveth - Nothing (The March of Death)
Mourning Beloveth - Anger's Streaming Arrows
Katatonia - Tomb of Insomnia
Desire - Frozen Heart, Lonely Soul
Paradise Lost - Crying for Eternity
Primordial - The Coffin Ships
Judas Priest - Beyond the Realms of Death
Dismember - And So Is Life
Lykathea Aflame - Land Where Sympathy is Air

My Dying Bride-my hope the destroyer. Sad and beautiful.

there's so many...
...all Serenades and Pentecost by Anathema...

The Cry of Mankind - My Dying Bride

Thus my heart weepeth for thee - Saturnus

Credence - Opeth

Night's Dew - Shape of Despair

High Hopes, Don't leave me now, Comfortably numb, Mother - Pink Floyd

etc...

I forgot High Hopes and Comfortably Numb...and "For My Fallen Angel" by my dying bride is awesome as well...
