Can anyone suggest good songs?

Lots of stuff by La Dispute. For example, Edward Benz 27 Times:
"When you came into the store, did you know you’d show me your scars?"
And King Park. My favourite part:
"Can I still get into heaven if I kill myself?
Can I still get into heaven if I kill myself?
Can I ever be forgiven 'cause I killed that kid?
It was an accident I swear it wasn't meant for him!"
Unravel, by TK. It's a Japanese song, but the lyrics are worth searching for a translation:
"Tell me; oh tell me, the way it works, who is that inside of me?
Here in this broken-down, broken-down world, you laugh, without seeing a thing"
Japanese again, Ikue Asazaki's Obokuri Eeumi. The lyrics are a haiku about the hardships of poverty and isolation.
Gary Jules' Mad World is a classic:
"And I find it kinda funny
I find it kinda sad
The dreams in which I'm dying
Are the best I've ever had"
Yuki Kajiura's Conturbatio (piano version)
Yugo Kanno's Inochi no Arikata
Daniel Veerapen's Abyss (First 2 minutes anyway; after that it got too loud for my taste. But it was still sad all the way)
Mark Mancina's 'Saya's Courage'
You could also try BIGBANG's Blue (Korean song). The lyrics don't fit your criteria of having a deep meaning, but the music has a pretty subdued, depressed atmosphere.
