Can you suggest me some depressing music?

When I write, I get much of my inspiration from music. Right now, I’m looking for songs that are depressing, sad, or dark. I love melancholy music.
Basically, songs that have struck a chord with you and/or made you emotional.
Songs that are truly deep and substantial whether it’s in the lyrics or the rhythm/beat.

Here are some examples of what I’m looking for:
How To Disappear Completely – Radiohead
Closer – Kings of Leon
Make This Go On Forever – Snow Patrol
Everybody Hurts – REM
Mad World – Gary Jules

Even if they’re not necessarily depressing, but represent something beautiful and meaningful, preferably at a slower pace. (I’m not really interested in anything too upbeat.)
Examples:
Breathe Me – Sia
Almost Lover – A Fine Frenzy
Hometown – Adele

Instrumentals are great as well.

Tell me what you’ve got. :)
