Best Break-Up Songs?

[Joanne Collins]

>I need a really, *really* good breakup song... but danceable.  
>Something slow.

I hope this isn't too late for your needs, but I had to suggest this one:
Sometimes Love Just Ain't Enough, Patti Smyth and Don Henley

>I thought about "Yesterday" (my favorite Beatles song)... but the 
>sentiment's all wrong there.  I need a song that speaks to a mutual 
>parting of the ways, even an amicable one.  

I think this one might fit very well in this context.

Here are the lyrics:

Now, I don't want to lose you, but I don't want to use you
just to have somebody by my side.
And I don't want to hate you,
I don't want to take you, but I don't want to be the one to cry.

And that don't really matter to anyone anymore.
But like a fool I keep losing my place
and I keep seeing you walk through that door.

(Chorus)

But there's a danger in loving somebody too much,
and it's sad when you know it's your heart you can't trust.
There's a reason why people don't stay where they are.
Baby, sometimes, love just aint enough.

Now, I could never change you, I don't want to blame you.
Baby, you don't have to take the fall.
Yes, I may have hurt you,  but I did not desert you.
Maybe I just want to have it all.

It makes a sound like thunder, it makes me feel like rain.
And like a fool who will never see the truth,
I keep thinking something's gonna change.

(Chorus)

And there's no way home, when it's late at night and you're all alone.
Are there things that you wanted to say?
And do you feel me beside you in your bed,
there beside you, where I used to lay?

And there's a danger in loving somebody too much,
and it's sad when you know it's your heart they can't touch.
There's a reason why people don't stay who they are.
Baby, sometimes, love just ain't enough.

Baby, sometimes, love... it just ain't enough.
Oh, Oh, Oh, No.

Joanne.

Look, you're my best friend, so don't take this the wrong way. In twenty
years, if you're still livin' here, comin' over to my house to watch the
Patriots games, still workin' construction, I'll fuckin' kill you. That's
not a threat. Now, that's a fact. I'll fuckin' kill you. Chuckie (Ben
