any other suggestions?

These are sad/regret type songs... it might not fit into your song criteria but, these are the songs I listen to when I need to cry:

End of the Road by Boys 2 Men (hehehe)
"It's unnatural, you belong to me, I belong to you."

Move On - Jet
"If you have only seen...what you mean to me."

A Lack of Color - Death Cab
"If you feel discouraged when there's a lack of color here, please don't worry lover, it's really bursting at the seams... this is fact not fiction, for the first time in years."

Hold Me Now - Thompson Twins
"I have a picture, pinned to my wall, an image of you and of me and we're laughing, we're loving it all. Look at our life now, tattered and torn, we fuss and we fight and delight in the tears that we cry until dawn..."

I Miss You - Blink 182
"Will you come home and stop this pain tonight?"

I Shall Believe - Sheryl Crow
"Please say, honestly, you won't give up on me..."

When I think of the rest, I'll post it.

I don't think anybody said this song. It's been a while by staind. This is a great song. I mean talks about losing love, getting over drugs, and nething else in particular.
