Recommend "fuck you songs"?

What are some songs that basically say "fuck both of you" when someone betrayed you and moved on to someone else like you never existed/like they never hurt you? OR revenge songs aimed at a narcissist? The more cutthroat, the better :)

And Ceelo Green's Fuck You is obviously on my list. Lily Allen's Fuck You isn't specific enough (just needed to get these out of the way).
