Beyoncé - "Green Light"

Beyoncé - "Green Light": "What the hell is going on here? As you may remember from a few weeks ago, I blogged Amerie's '1 Thing' as a guilty pleasure, but one that was in a heavy Beyoncé/Destiny's Child mold. Well, now on the new Beyoncé, we have this track...which bites a vocal element from '1 Thing' wholesale. Is this some kind of mutual-admiration society that I missed the 411 on?"
