It's just that is pains me to see stank given less weight than hair and hand gestures!
Ok, here's an idea. What if it's not Beyonce's fault? What if it's our fault? What if it was once the case that, to be taken seriously, you had to possess at least a certain baseline level of stank? (Let's call it the Gladys line.) Later we relaxed our standards for the extremely talented but stank-challenged Celines, Mariahs, and Whitneys, and left the door open for the Beyonces and even the Jordin Sparks, who are just plain boring. A theory!
Do you think the concept of stank has any musical content? I certainly think it does, which is why I think the example you chose to illustrate it is a poor one. To me stank is a quality that emanates from the interpretation of the melody. To me, stank is something like this. Yes! And it's a damn shame that it has such negligible value in the contemporary diva economy. And yes, I registered solely so that I could post that Etta James clip.
