People people,this is Beyonce we're talking about. She has the ability to turn the floppiest 1st single into the solid Top 10 smash with just 1 performance. If she underperforms that will be in Deja Vu style. Beyonce is smart business woman who knows exactly what's she doing. Do you really think she would work on an album for a long time and release it knowing that there isn't at least 1 'Irreplaceable' smash hit on it? Yeah right. Don't make me laugh.
All those who are praying for her to flop (more than half of ATRL) can keep dreaming because it's simply not going to happen. Because she's not Christina, she's not Britney, she's not Katy Perry, she's not Gaga...she's Beyonce.
