i dont want you back

I'm looking for this song if anyone has it they'd like to share it. I only know the title (I think its the title) "I don't want you back", it's a mix I heard a long time ago ('87-'91) the sound of the girls voice is similar (if it's not the same) as Corina or Fascination. Anyone know the title...

Where can I get this song? What compilation, what album is it on? Thanks.
