I think the meanest love song is Alanis Morissette's "You Oughta Know." You can hear that the love is still there even though the bitterness is beginning to take the upperhand in the battle. Find the lyrics below. Hope this helps.
You Oughta Know - Alanis Morissette
I want you to know, that I'm happy for you
I wish nothing but the best for you both
An older version of me
Is she perverted like me?
Would she go down on you in a theater?
Does she speak eloquently?
And would she have your baby?
I'm sure she'd make a really excellent mother
'Cause the love that you gave that we made
Wasn't able to make it enough for you to be open wide, no
And every time you speak her name
Does she know how you told me you'd hold me
Until you died, 'til you died?
But you're still alive
And I'm here to remind you
Of the mess you left when you went away
It's not fair to deny me
Of the cross I bear that you gave to me
You, you, you oughta know
You seem very well, things look peaceful
I'm not quite as well, I thought you should know
Did you forget about me Mr. Duplicity?
I hate to bug you in the middle of dinner
It was a slap in the face, how quickly I was replaced
Are you thinking of me when you f#*k her
'Cause the joke that you made in the bed, that was me
And I'm not going to fade
As soon as you close your eyes, and you know it
And every time I scratch my nails down someone else's back
I hope you feel it ...can you feel it?
