I'm usually pretty sharp when it comes to identifying samples too. I'm not 50 but I'm not a youngster either. I would have to hear the basslines next to each other to believe it. Is it supposed to be the same or just kinda similar?
Now that I think about it, the drums are used. Or more noticably, the toms.
Whatever the case may be, the Truth Hurts song is filthy and I can't wait to hear the entire album.
