I'm afraid i'm too lazy and far too tired at the moment to post the actual youtube videos of the songs in the thread, but i'll list a few for you to look up at your own convenience.
Everybody Hurts - REM
It Means Nothing - Stereophonics
My Immortal - Evanescence
Forgiven - Within Temptation
Carry You Home - James Blunt
Pictures of You - The Cure
Charlotte Sometimes - The Cure
Happy Ending - Mika
Spark - Tori Amos
And one song that's always made me deepy sad for some reason is
Everlasting Love - The Love Affair
I don't know why... i always imagine it being played at a funeral, when you're looking back over the memories of the person after the service. The tune just really gets to me.
