Cher sings it. Maybe I'm thinking of the wrong song, now... Does it go something like this?

No matter how hard I try
You keep pushing me aside
And I can't break through
There's no talking to you
It's so sad that you're leaving
It takes time to believe it
But after all is said and done
You're gonna be the lonely one

Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enough
Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enough

What am I supposed to do
Sit around and wait for you
Well I can't do that
And there's no turning back
I need time to move on
I need a love to feel strong
'Cause I've got time to think it through
And maybe I'm too good for you

Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enough
Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enough

Well I know that I'll get through this
'Cause I know that I am strong
I don't need you anymore
I don't need you anymore
I don't need you anymore
No I don't need you anymore

Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enogh
Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enough
Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enough
Do you believe in life after love
I can feel something inside me say
I really don't think you're strong enough

*snicker*

Oh, and with what kind of music? It's sort of techno-sounding, with a *thump thump thump* bass beat, and her voice does this weird fade out and stuff.

Actually I don't really know.
I only know that one line where her voice gets all eletrical. I think its from a Cher album comerical or something like that. But yeah, since Cher has been singing for so long I can excuse myself for thinking it was from the 80s.

*nod me*
